New in version 4.1
June 22nd, 2015
- Anyway, since rc8 we've had truly small changes, mainly some final driver fixups (HDA sound, drm, scsi target, crypto) and a couple of small misc fixes. The appended shortlog is probably one of the shortest ones ever.
New in version 4.1 RC8 (June 15th, 2015)
- But the bulk is (as usual) drivers, and no, that's not from the md camp (those fixes are very small). Mostly ethernet, slave-dma, and spund. But some drm fixes and random other noise too. There's some generic networking fixes as well, and random small stuff.
New in version 4.1 RC7 (June 8th, 2015)
- A lot of it is one-liners, with a few slightly bigger patches to some architecture files (x86 perf constraints, some sparc updates) and staging drivers.
New in version 4.1 RC6 (June 1st, 2015)
- This is about half drivers (mainly scsi target, networking, and graphics, plus the aforementioned raid and dm changes, with other random fixes). The rest is fairly evenly split between architecture updates (alpha stands out), filesystem updates (xfs, cifs and overlayfs) and "misc" (networking, turbostat tool update, documentation).
New in version 4.1 RC5 (May 25th, 2015)
- We've got about two thirds driver updates (gpu, infiniband, sound, networking, scsi, thermal), and almost half of the remainder is networking updates. The rest is mostly arch updates and some filesystem fixes.
New in version 4.1 RC4 (May 18th, 2015)
- So here it is, last-minute fix and all. The -rc4 patch is a bit bigger than the previous ones, but that seems to be mainly due to normal random timing - just the fluctuation of when submaintainer trees get pushed, and rc4 has fixes from Greg to various driver trees _and_ the networking fixes from Davem, so the slightly larger size isn't indicative of any sudden problems.
- But while drivers and networking dominate the changes, there's a random smattering of other changes. Filesystems (btrfs, nfsd) and architecture updates (mainly arm, arm64 and mips) and some other misc changes.
New in version 4.1 RC3 (May 10th, 2015)
- As you can tell, it's mostly drivers, with a smattering of arch updates (mostly ARM). And a smattering of misc stuff: perf tooling, documentation, filesystems. The infiniband update is a noticeable chunk of the drivers, we had some delayed stuff there due to maintainership changes.
- Nothing particularly scary or worrisome going on, although there are little fixes all over. Some of them are regressions from this merge window, and some of them are older. And some of them are so old that I almost thought "if it's been broken since 2011, and you only noticed now, maybe it could have waited for the next merge window". You know who you are (and others will too, if they read the commit messages - your shame is out there).
New in version 4.1 RC2 (May 4th, 2015)
- As usual, it's a mixture of driver fixes, arch updates (with s390 really standing out due to that one prng commit), and some filesystem and networking. The attached shortlog gives the details, there's nothing particularly worrisome here. So far 4.1 looks fairly normal.
New in version 4.1 RC1 (April 27th, 2015)
- The bulk of the changes are to drivers (just under 60% of the patch), with arch updates being about 20% of it all, and the rest is spread all over.
New in version 4.0 RC7 (April 6th, 2015)
- It's about three quarters driver updates (the bulk of it being network drivers, but there's stuff all over: gpu, iio, input, usb...). The rest is some small x86 fixes, some networking, a lazytime fix and documentation.
New in version 4.0 RC6 (March 29th, 2015)
- Things are calming down nicelly, and there are fixes all over. The NUMA balancing performance regression is fixed, and things are looking up again in general. There were a number of i915 issues and a KVM double-fault thing that meant that for a while there I was pretty sure that this would be a release that will go to rc8, but that may be
- unnecessary. Apart from the aforementioned issues, the bulk of this is mostly small misc driver fixes and architecture updates. The shortlog gives more of a flavor of what's been going on.
New in version 4.0 RC4 (March 16th, 2015)
- Nothing particularly strange going on this week either, with perhaps just a slightly larger-than-expected ARM SoC update. So "just" half of the patch is driver updates, with about half of the rest being ARM changes.
- The rest is the usual random mix of fixes - some other architectures (s390, nios2), some networking, core kernel and vm, some documentation updates. Nothing particularly stands out here. Shortlog appended, I think we're doing fine for where in the release cycle we are.
New in version 4.0 RC3 (March 9th, 2015)
- Size-wise, this is also fairly normal, not as tiny as rc2. Easily explained by getting the fixes from both David and Greg (since networking and drivers tend to be the two single biggest parts).
- And the patch distribution is quite standard too: about two thirds drivers (gpu, networking, usb, staging, sound, misc), with the rest being filesystems (mainly nfs, btrfs), architecture updates (arc, x86, arm, powerpc), networking, and Documentation.
New in version 4.0 RC2 (March 4th, 2015)
- It's been a very quiet week, for being this early in the release process. Sure, 3.19-rc2 was even smaller, so it continues a trend, but that was the xmas week. I hope this low volume is just because the 4.0 merge window itself was somewhat calmer than most recent releases. But I suspect the real reason is that the driver and networking trees from GregKH and davem are pending, and didn't make rc2.
New in version 4.0 RC1 (February 23rd, 2015)
- The live patching infrastructure made some news, but my personal favorite features are actually some vm cleanups, where this release is getting rid of the largely unused non-linear remapping code (replaced with just emulating it with lots of smaller mappings) and unifies the NUMA and PROTNONE handling for page tables.
New in version 3.19 RC7 (February 2nd, 2015)
- Fairly normal rc statistics - about 50% drivers, 20% arch updates (mostly arm and arm64, some x86), with filesystems showing up a bit more than usual (largely due to some quota changes), and the rest being "misc" - perf tooling, some minor kernel and vm changes etc.
New in version 3.19 RC6 (January 26th, 2015)
- The statistics look very normal, with the patch being about 70% driver changes (a Dell laptop platform driver revert being the biggest single patch, but there's networking, media, gpu, gpio, sound..) and about 14% arch updates (x86 and arm are the biggest ones, but there are small updates to others too) and the rest is mostly scattered all over
- (documentation updates, some networking, some filesystem changes - mainly btrfs, etc etc).
New in version 3.19 RC5 (January 18th, 2015)
- The arm64 vm bug that I mentioned as pending in the rc4 notes got fixed within a day of that previous rc release, and the rest looks pretty standard. Mostly drivers (networking, usb, scsi target, block layer, mmc, tty etc), but also arch updates (arm, x86, s390 and some tiny powerpc fixes), some filesystem updates (fuse and nfs), tracing fixes, and some perf tooling fixes.
New in version 3.19 RC4 (January 11th, 2015)
- Apart from the kgdb patches showing up as some uncommon work under kernel/debug/, things look fairly normal: mostly driver updates (gpu, pinctrl, hid, networking), architecture updates (mainly x86 this time, some minor arm stuff), and some tooling fixes (mainly perf).
New in version 3.19 RC3 (January 6th, 2015)
- A bit over three quarters of the changes here are drivers - mostly networking, thermal, input layer, sound, power management. The rest is misc - filesystems, core networking, some arch fixes, etc. But all of it is pretty small.
New in version 3.19 RC1 (December 21st, 2014)
- In the "big picture", this looks like a fairly normal release. About two thirds driver updates, with about half of the rest being architecture updates (and no, the new nios2 patches are not at all dominant, it's about half ARM, with the new nios2 support being less than 10% of the arch updates by lines overall). The remaining one sixth is "misc": networking, header updates, documentation, filesystems, tooling, and core kernel (in pretty much that order).
New in version 3.18 (December 8th, 2014)
- It's been a quiet week, and the patch from rc7 is tiny, so 3.18 is out.
- I'd love to say that we've figured out the problem that plagues 3.17 for a couple of people, but we haven't. At the same time, there's absolutely no point in having everybody else twiddling their thumbs when a couple of people are actively trying to bisect an older issue, so holding up the release just didn't make sense. Especially since
- that would just have then held things up entirely over the holiday break.
- So the merge window for 3.19 is open, and DaveJ will hopefully get his bisection done (or at least narrow things down sufficiently that we have that "Ahaa" moment) over the next week. But in solidarity with Dave (and to make my life easier too ;) let's try to avoid introducing any _new_ nasty issues, ok?
New in version 3.18 RC7 (December 1st, 2014)
- The rc7 patch looks very normal, with two thirds being drivers (spread all over: usb, networking, staging, thermal, gpu, sound..) and half of the remaining being arch updates (mostly mips, arm, powerpc). The remaining is mainly networking and some filesystem fixes (nfsd and btrfs).
New in version 3.18 RC6 (November 24th, 2014)
- The good news is that things are generally calming down, and most of the changes are smallish regression fixes here, with a smattering of stable patches. About half drivers (networking, sound, pci, infiniband, etc), with architecture updates (x86, mips, arm), and networking code being about half of the rest. And the last quarter is "misc": filesystem fixes, documentation, scheduler.
New in version 3.18 RC5 (November 17th, 2014)
- About 55% drivers (networking, gpu, cypto, thermal, sound), 15% arch updates (xtensa, x86, arm, parsic, sparc), and the rest is a mostly a mix of netwoorking, filesystem, VM, documentation and tracing updates.
New in version 3.18 RC3 (November 3rd, 2014)
- Lots and lots of small stuff, with drivers accounting for the bulk of it (both in commits and in lines), but networking and core kernel showing up too. Nothing particularly stands out.
New in version 3.18 RC2 (October 27th, 2014)
- nd to be honest, we've had bigger rc2's in history. Not recently, though. Both 3.3 and 3.4 had big -rc2 releases, and 3.15 (which was the largest release ever, iirc) came reasonably close.
- At least _part_ of the size is the very long-delayed overlayfs merge that I already mentioned in the rc1 release message as being pending. Let's see how much fallout that all causes, but it's been around for a long time (partly because it needed various vfs-layer things to integrate cleanly), and I think it's in good shape. Knock wood.
- So at least partially as a result of that overlayfs merge, about a third of the patch is filesystems. It's not _just_ overlayfs, though, there was a late ext4 merge request that I think is actually bigger, at least partly due to some extent handling refactoring.
- The rest is the more usual driver updates (thermal, watchdog, scsi target, ACPI & PM, misc other updates) and architecture updates (arc, arm, powerpc, mips, x86). Some documentation and include file updates rounds out the rest.
New in version 3.17 RC7 (September 29th, 2014)
- There's stuff all over here. The i2c part of the patches stands out a bit because of some code movement, but apart from that the diffstat looks pretty calm. About 60% drivers, with the rest being a mix of documentation, arch, filesystem and networking. Nothing
- really particularly stands out, but it is just bigger than I was happy with doing a release without another rc.
New in version 3.17 RC6 (September 22nd, 2014)
- A bit more than half is drivers (gpu, sound, iio, media, usb), just under a third is arch updates (arm, mips, x86), and the rest is mainly filesystem updates (gfs2, cifs, btrfs, nfs).
New in version 3.17 RC5 (September 15th, 2014)
- The rc5 changes is about half drivers (networking, gpu, usb, input, ata..) with the rest being mostly a mix of filesystem updates (the aforementioned performance thing in the core vfs layer, but also some NFS export issues found by Al and misc other stuff), architecture updates (arm, parisc, s390) and core networking. And a smattering of other. Shortlog appended.
New in version 3.17 RC4 (September 8th, 2014)
- For a short while there, this week was really nice and calm, but that was mostly because the "linux-foundation.org" entry fell off the DNS universe, and my mailbox got very quiet for a few hours. The rest of the week looked pretty normal.
- "Pretty normal" isn't bad, though, and I'm not complaining. There is nothing particularly big or scary going on - we had a quick scare about a stupid compat layer bug, but it seems to have been just a false positive and resulted in some added commentary rather than any
- real code changes.
- The diffstat is pretty reasonable, and it's fairly spread out. We have the usual arch and driver updates, but there's actually more changes under fs/ than under either of those. That's largely due to just a late f2fs update, which I decided I couldn't be bothered to get too upset about, most of it being pretty clear-cut fixes, with just a few cleanups mixed in.
- And really, if the f2fs changes look biggish, it's mostly because the rest is pretty small.
- Let's hope it all stays calm. I do note that neither Greg nor Davem ended up sending me anything for rc4, which is probably the _real_ reason why it's pretty calm and small.
New in version 3.17 RC3 (September 1st, 2014)
- I'm back to the usual Sunday release schedule, and -rc3 is out there now. As expected, it is larger than rc2, since people are clearly getting back from their Kernel Summit travels etc. But happily, it's not *much* larger than rc2 was, and there's nothing particularly odd
- going on, so I'm going to just ignore the whole "it's summer" argument, and hope that things are just going that well.
New in version 3.17 RC2 (August 26th, 2014)
- So I deviated from my normal Sunday schedule partly because there wasn't much there (I blame the KS and LinuxCon), but partly due to sentimental reasons: Aug 25 is the anniversary of the original Linux announcement ("Hello everybody out there using minix"), so it's just a good day for release announcements.
- Anyway, for being an rc2 it's pretty small, and I can always hope that things stay that way. It's about 60% drivers (drm, networking, hid, sound, PCI), with 15% filesystem updates (cifs, isofs, nfs), 10% architectures (mips, arm, some minor x86 stuff) and the rest is "misc" (kernel, networking, documentation).
New in version 3.17 RC1 (August 16th, 2014)
- I'm going to be on a plane much of tomorrow, and am not really supportive of last-minute pull requests during the merge window anyway, so I'm closing the merge window one day early, and 3.17-rc1 is out there now. Well, it's been out for a while now, but the network was bad enough where I'm traveling that I couldn't get this *announcement* out.
- Anyway, this merge window was slightly smaller than the last few ones, probably due to summer slowdowns in the northern hemisphere. Which is not to say that it was *small* - the last few releases have been larger than usual, this one is just fairly average. It's certainly big enough that I can't post the shortlog, so as usual this just appends
- the "mergelog" where the people credited are the people I pulled from, not necessarily the people who wrote the code.
- Changes all over the place, but no huge new architectures or filesystems. About three quarters of the changes are drivers, and of the rest, roughly half is architecture updates, with the rest being misc core changes (networking, filesystems etc).
- The upcoming week is the kernel summit, so I'm guessing rc2 will be fairly small, but we'll see how that goes.
New in version 3.16 RC6 (July 21st, 2014)
- Week by week, we're getting to what is supposed to be the last rc's, but quite frankly, things aren't calming down the way they are supposed to.
- That was already true for rc5 - it was bigger than rc4. That didn't worry me all that much, because rc4 was really pretty small. But now rc6 is out, and it's bigger than rc5 was, and it's not even all trivial stuff. That's not how this is all supposed to work.
- Anyway, rc6 still isn't all *that* big, so I'm not exactly worried, but I am getting to the point where I'm going to start calling people names and shouting at you if you send me stuff that isn't appropriate for the late rc releases. Which is not to say that people did: while rc6 is bigger than I wished for, I don't think there's too much obviously frivolous in there. But I'll be keepign an eye out, and I'll be starting to get grumpy (or grumpiER) if I notice that peopel aren't being serious about trying to calm things down.
- Regardless, rc6 itself ends up having changes pretty much all over: drivers (much of it networking, but there's gpu, there's infiniband, you name it), filesystems (late nfs fixes, xfs, fuse, gfs2, btrfs), core networking code, etc etc. The shortlog is appended for those interested in (an overview of) the details.
- So go get the latest rc and kick the tires, to see that nothing has fallen through the cracks, ok?
New in version 3.16 RC5 (July 14th, 2014)
- Things are looking normal, and as usual, I _wish_ there was a bit less churn going on since it's getting fairly late in the rc cycle, but honestly, it's not like there is anything that really raises any eyebrows here.
- The bulk of this is drivers - with acpi and gpu sticking out, if only by a hair. It's pretty mixed, really (hid, hwmon, iio, thermal, clk drivers, libata, pinctrl, etc). There's the usual architecture updates (mostly arm, some powerpc), there's some docbook fixes, and there's a couple of filesystem fixes (f2fs, kernfs and ext4). With a smattering of small core fixes (mainly cgroup) too.
New in version 3.16 RC3 (June 30th, 2014)
- We're back on a Sunday release schedule, and things are looking reasonably normal.
- There's perhaps relatively less driver updates than usual, with most of them being pretty small, but that is probably just a timing thing (ie Greg didn't send his USB/staging changes this week, so driver changes are mostly gpu, networking and sound).
- As a result misc architecture updates (mips, powerpc, x86, arm) dominate the diff, and there are various random other updates. We've got filesystem updates (aio, nfs and ocfs2), a small batch of mm fixes from Andrew, some networking stuff.etc.
- The shortlog gives a feel for the changes. The most noticeable to actual users are probably the unbreaking of direct block device read accesses on 32-bit targets, and some x86 vdso regression fixes that caused problems. The rest probably didn't end up affecting very many
- people, but it's all proper fixes..
New in version 3.16 RC2 (June 22nd, 2014)
- It's a day early, but tomorrow ends up being inconvenient for me due to being on the road most of the day, so here you are. These days most people send me their pull requests and patches during the week, so it's not like I expect that a Sunday release would have made much of a difference. And it's also not like I didn't have enough changes for making a rc2 release.
- Anyway, enough excuses. 3.16-rc2 is out, and contains the usual assortment of fixes all over the map. The most unusual part at this point is how the sparc changes stand out (at almost 40% of the patch by bulk), but they are basically all just sparse warning cleanups.
- Similarly, some Nouveau drm changes standing out size-wise, but again those are largely due to small firmware fixes resulting in big generated changes. The actual real changes are fairly small.
- Ignoring those two unusually large changes (in lines), everything else looks fairly normal. There are driver changes, some tooling updates (particularly perf), and various other arch updates (arm, s390, unicore32, x86..). And just misc random stuff all over the place - rtmutex, btrfs, yadda yadda.
- The shortlog is not tiny, but small enough to include here, so you can see the details there if you care.
New in version 3.15 RC8 (June 2nd, 2014)
- I was really hoping that rc7 would be the last rc, but it appears that reality is once against conspiring against my well-laid plans, and is forcing me to do an rc8. It's not like there were a lot of changes, but the last-minute dcache fixes in particular made it not really sane to just make a final release without another week of testing.
- Now, normally, an rc8 isn't really a big deal - 3.15 is one of the biggest (if not _the_ biggest) releases in a long time, and we do rc8's with some regularity. It may not be every release, but I think it's about a fifty-fifty chance whether any particular release goes to rc8. So I shouldn't be upset, and I'm certainly not surprised.
- No, the real reason I was hoping that we wouldn't need to do an rc8 for 3.15 is that school is out in two weeks, and we're doing our family vacation immediately after that. And I'd hate to have yet another "Linus is traveling during the merge window" thing. Normally I have been luckier with my trips than that.
- Now, I'll have internet, and I *could* do the merge window while on vacation with the family. I'd just prefer not to.
- SO... Let's try something new. I suspect most people are ready to start the merge window, and we could try how it would be to overlap the first week of the merge window with the last week of the previous release. Most of the submaintainers already use git branches actively, so I doubt anybody will find it too confusing if I end up having a "next" branch for a week that contains the stuff I pull for 3.16.
- So let's try to see how well that works - the last weeks of the release tends to be me just waiting around to make sure nothing bad is happening, so doing this kind of overlapping development *should* work fine. Maybe it works so well that we'll end up doing it in the future even if there *isn't* some kind of scheduling conflict that makes me want to start the merge window before I'm 100% comfortable doing the release for the previous version.
- And it's not like I think rc8 is in any way broken. I just don't feel comfortable doing a real 3.15 release without a _bit_ more time for people to use the fixed dentry code.
- Anyway, apart from the dcache changes, there's a lot of random smaller stuff. One one-liner in particular is interesting: Minchan Kim had a load that basically ate up all the kernel stack on x86-64, and so this finally does something I've been trying to delay for a long time - it expands the stack to 16kB. I think all other 64-bit architectures have
- done that a long time ago already, so it's not exactly shocking, but it's a somewhat fundamental change on one of the main architectures.
New in version 3.15 RC6 (May 22nd, 2014)
- Due to travels and related lack of internet access, the rc releases haven't been following the normal Sunday release cycle, and since I caught up with what happened while I was off-line, rather than wait until next Sunday to reset to the normal cycle, I'm just releasing rc6 now mid-week from Tokyo.
- With rc5 being a couple of days early, and rc6 being several days late, we had almost two weeks in between them. The size of the result is not twice as large, though, hopefully partially because it's getting late in the rc series and things are supposed to be calming
- down, but presumably also because some submaintainers just didn't send their pull requests because they knew I was off-line. Whatever the reason, things don't look bad.
- The patch distribution looks pretty normal too. Mostly drivers (acpi, sound, media, i915, clk, pci..) with the bulk of the rest being various arch updates (notably MIPS, but arm and parisc too). And a smattering of other random stuff in filesystems and core kernel code.
- Anyway, depending a bit on what else is pending, I'll probably stretch out rc7 to get back to the normal Sunday schedule, and depending on how things look by then that may or may not be the last rc.
New in version 3.15 RC5 (May 9th, 2014)
- Yes, I'm aware that this is two days early. The normal schedule has been for me to do Sunday releases, but this time around I have a combination of travel (which would have pushed the release to Saturday morning from the airport as is oft my wont when traveling) and the fact that rc5 has actually already grown to be larger than rc3 or rc4 were.
- So instead of pushing it to the last minute before I board a plane and am off-line for a week, I decided that there is absolutely zero reason for that kind of just-under-the-wire release timing. I'd rather do a leisurely release on a Friday afternoon than a hurried one tomorrow morning before then disappearing for a week.
- Anyway, enough explaining. rc5 is out there, and while I'd have been happier if it had been as small as rc4 was, it seems to all be solid fixes (famous last words). The interesting dcache list corruption I mentioned as being pending for rc4 is in, and it would be lovely if you have any VFS layer stress-testing that interacts with memory pressure, but the race was tiny to begin with, and the fix actually cleaned things up a lot and removed more lines than it added, so I feel good about it.
- Apart from that one interesting really core change (where "really core" is defined as "an area I personally care about and muck around with", and not meant to be a value statement in any other way ;), it all looks boringly familiar: 55% drivers, 20% architecture updates, and 25% misc (filesystems, core networking, VM, etc).
- And while rc5 may be bigger than rc3/4 were, it's not like it is worrying. This merge window was bigger than most, and the fact that rc5 is then slightly bigger than most isn't something that worries me overmuch. And since rc4 was smaller than usual, it all evens out. But I really *will* be entirely nreachable all next week, so get your testing in, because the -git tree will be very quiet.
New in version 3.15 RC4 (May 5th, 2014)
- Nothing particularly unusual going on. 45% drivers (drm, sound, md, pin-control, acpi etc), 40% arch (mainly powerpc/powernv, but x86 and arm too), 15% misc (perf tooling, documentation updates, core code). The appended shortlog gives some kind of overview of the details without being _too_ big.
- There's a few known things pending still (pending fix for some interesting dentry list corruption, for example - not that any remotely normal use will likely ever hit it), but on the whole things are fairly calm and nothing horribly scary. We're in the middle of the calming-down period, so that's just how I like it.
- But the more testing we get, the better, so please do give this a whirl.
New in version 3.15 RC2 (April 22nd, 2014)
- It's been a week, so here's another rc. And while -rc1 was one of the biggest rc's in memory, rc2 looks fairly normal. We had a few niggling issues fixed, but it really wasn't anything horribly worse than usual. It might be a *bit* bigger than most -rc2's, but let's wait to see after rc3 whether things are actually busier than usual. Quite often rc2 is calmer than rc3, with it taking a week for some issues to show up.
- As to what happened during last week: the *bulk* of the rc2 patch is actually the removal of the rtl8187se staging driver, since there's a proper non-staging one. That's literally just over half of the actual patch. But even if you ignore just that bulk removal, other driver
- changes account for about two thirds of the rest (gpu, networking, fbdev file renames, ipmi, infiniband, pincontrol... you name it). The drm stuff is probably most noticeable.
- Outside of drivers, we've got the usual arch updates (mostly x86 and s390, some parisc) and some Documentation updates. Various networking fixes and filesystem updates (cifs, sysfs, xfs). And some tooling stuff.
New in version 3.14 (March 31st, 2014)
- Deadline scheduling class for better real time scheduling
- zram: Memory compression mechanism considered stable
- Trigger support for tracing events
- Userspace probes access to all arguments
New in version 3.14 RC6 (March 10th, 2014)
- We're getting closer to the end of the rc cycle, and I have to admit that I would have wished for a less bumpy ride.
- There haven't been any huge problems, but there's been quite a few small bumps that shouldn't happen this late in the release cycle. And rc6 is noticeably bigger than rc5 was, as well.
- So I'm really hoping that the upcoming week will be calmer, because otherwise I'll start thing rc8 and even rc9..
- That said, there's nothing really fundamentally scary here. Small stupid mistakes, and a few late reverts of commits that turned out to not be so great, but the bulk is trivial fixes. So I'm still reasonably optimistic.
New in version 3.14 RC5 (March 3rd, 2014)
- Things were fairly calm, and fairly normal. Drivers account for just under 60% of the patch (sound dominates due to a couple of patches that are larger but trivial, but there's various misc oneliners all over). The rest is mostly arch updates (mainly powerpc and xtensa), and then there's a smattering of small stuff elsewhere.
New in version 3.14 RC4 (February 24th, 2014)
- The biggest patch in here (accounting for about a sixth of the total) is just DaveJ re-indenting a reiserfs file. Ignoring that whitespace cleanup, the rest is mostly the usual mix of drivers, networking and some architecture updates.
New in version 3.14 RC2 (February 10th, 2014)
- It's been pretty quiet, actually, which should make me happy. But I have a suspicious nature, and I'm going to wait to see if the other shoe drops, and people are just lulling me into a false sense of security. Because I know kernel developers, and they are sneaky. I suspect Davem (to pick somebody not at random) is giggling to himself, waiting for this release message, planning to send me some big-ass pull request tomorrow. Because that's the kind of people you guys are.
- Anyway, what little there was looks normal: roughly two thirds drivers (gpu, block, media, misc), with almost half the remaining patches being architecture updates (x86, s390 and arm64). With the rest being filesystems (vfs, nfs, ocfs, btrfs and some kernfs fixes), some mm noise, and tooling (perf).
- Shortlog appended, which doesn't always happen for rc2.
New in version 3.13 RC8 (January 12th, 2014)
- rc8 has the usual "two thirds drivers, one third random" mix, with "random" having some arch updates (arm and parisc this time), but is mostly network updates. A fair chunk of the driver changes are network drivers too, for that matter.
New in version 3.13 RC7 (January 5th, 2014)
- In this rc, about half of the updates are networking (both drivers and core), and the rest is a mix of other drivers (gpu, input, pci core, some random of patch as well) and arch updates (s390 and powerpc, some arm noise). And with some random stuff thrown in (cifs/gfs2, some mm stuff from Andrew, etc).
New in version 3.13 RC6 (December 30th, 2013)
- As expected, things have been quiet over the holiday week. So various small random updates: drivers (infiniband, gpu, cpufreq, libata, block), some small filesystem fixes (ext4/jbd2), and a few ARM SoC things. Tiny x86, percpu and cgroup fixes.
New in version 3.13 RC5 (December 22nd, 2013)
- Ho ho ho, Christmas is almost upon us, and -rc5 is the last rc before most of us gorge ourselves into insensibility. Or cry into our lonely beers. Or go out for Chinese food. Or whatever you happen to do.
- Things seem to be slowly calming down, and I expect that the next week is going to be calmer yet, for all the obvious reasons. This might also be a good time to say that even _if_ things continue to calm down, I think we'll be going to at least -rc8 regardless, since LCA is fairly early this year, and I won't be opening the merge window for 3.14 until after I'm back from those travels.
- Anyway, about rc5: about 40% drivers (gpu, networking, sound, misc-you-name-it), 15% architecture updates (mainly powerpc this time), 10% filesystems (ceph/cifs), 10% documentation, and the rest "misc", including some core kernel (scheduler) and mm (numa) fixes.
- Nothing really exciting stands out. The bugs I was involved with were all sufficiently subtle and unusual that I didn't feel like they raised any red flags at this point, which is just how I want it. It's the "how did that ever even pass cursory testing" bugs that make me upset, and if those existed, people were appropriately ashamed and quiet about them ;)
- So despite me planning on dragging out the rc's a bit, there doesn't actually look to be any real technical reason for doing that, at least so far. It all looks good, so please jump in and help test,
New in version 3.13 RC4 (December 15th, 2013)
- So I delayed this a couple of days to get back to my normal Sunday release schedule, but I'm not entirely happy with the result. Things aren't calming down the way they should be, and -rc4 is bigger than previous rc's. And I don't think I can just blame the two extra days.
- Anyway, what that means from a practical standpoint is that I'm going to be *very* grumpy at anybody who sends me unnecessary crap. If it's not regression or marked for stable, then just don't send it to me. Because you *will* be called names if you can't follow those simple rules. Comprende?
- Anyway, the bulk of changes for rc4 is drivers (notably networking and gpu, but there's usb, input and media driver updates too). Aside from that, there are the usual arch updates (mainly ARM) and the slightly less usual selinux updates. And generic networking, with some random stuff thrown in for good measure. The shortlog isn't very short, but it's appended for your reading pleasure.
- We're obviously heading for the holiday season, and I'm really hoping that will help calm things down too for the rest of the release candidates...
New in version 3.13 RC3 (December 6th, 2013)
- .. I'm still on a Friday release schedule, although I hope that changes soon - the reason I didn't drag this one out to Sunday is that it's already big enough, and I'll wait until things start calming down.
- Which they really should, at this point. Hint hint. I'll start shouting at people for sending me stuff that isn't appropriate as we're starting to get later into the release candidates.
- That said, it's not like rc3 is somehow unmanageably large or that anything particularly scary has happened. I'd have *liked* for it to be smaller, but I always do.. And nothing particularly nasty stands out here.
- The bulk here is drivers (net, scsi, sound, crypto..) and ARM DT stuff, but there's the usual randon stuff too, with arch updates (pa-risc, more ARM, x86) and some filesystem and networking updates.
New in version 3.12 RC7 (October 28th, 2013)
- The KS week is over, and thus the seventh - and likely the last - rc for 3.12 is out, and I'm back on the normal Sunday schedule.
- The slowdown in -rc sizes sadly reversed itself here, mostly due to the networking updates that hadn't come in for rc5-rc6. You can see that in the diffstat, with more than 50% being networking (both driver and core) patches. The rest is generally other drivers (gpu, media, scsi, thermal, HID) and some smaller arch updates (s390, parisc, x86).
- Nothing looks particularly shocking, though, so we're still on track for 3.12. Which does mean, that with me having more travel coming up, the 3.13 merge window will likely end up being a bit messed up.
- I can usually schedule around these kinds of things, but with two different trips and just a week in between, I have the choice of either just delaying 3.12 for no good reason, or just saying "ok, we'll just keep the merge window open a bit longer because I won't be able to be as responsive as I should be".
- But who knows. If something particularly worrisome comes up during the upcoming week, I might just say "Ok, we'll do an rc8 instead". So I'm keeping my options open.
New in version 3.12 RC6 (October 19th, 2013)
- I'm at PDX, about to fly out to the kernel summit, and it has almost become a tradition to do an rc release using the airport wifi. So here it is..
- The patch is still busily being pushed out, but the git trees are up-to-date, and the tar-file should already be out. Nothing major happened last week., and the upcoming week is likely to be quiet too, since a lot of core maintainers will be in Edinburgh for the KS.
- Shortlog with more details appended, but the overview is just mainly driver updates. USB, infiniband, acpi.. Some documentation and Cifs updates, and the rest is random noise.
New in version 3.12 RC3 (September 30th, 2013)
- I'm back to a Sunday release schedule, so here it is, rc3.
- Nothing really special stands out. There's a fair amount of churn in mm, which is unusual at this point, but that's all reverts: during the merge window Andrew sent some changes that were still being discussed, and we're reverting them for now.
- If you ignore the mm changes, the rest looks very normal: the bulk is drivers (gpu, dm/bcache, usb, sound..), with the usual sprinkling of architecture (powerpc, x86, arm, mips) and filesystem (udf, xfs, reiserfs) changes. And some perf tooling.
- And we had some performance-tweaking of the new lockref support for ARM and s390.
- On the whole, nothing really appears very scary. Go forth and test.
New in version 3.11 RC4 (August 5th, 2013)
- We've got some arch updates (arm, parisc), but most of this is drivers (mostly networking, usb and some drm updates). There's also some core networking changes. And the printk code movement looks big if you don't do git renames (ie like the patches I upload).
New in version 3.11 RC3 (July 29th, 2013)
- And please just forget about me telling you people to get back to work last week. You got. -rc3 has about 50% more commits than -rc2 did. Part of it is that a few people missed rc2, but part of it is that people just sent me more. Please stop. It's summer. It's nice outside. Take the kids to the pool or something. Send me just regression fixes.
- Otherwise I'll have to start shouting at people again.
- Anyway, remember how I asked people to test the backlight changes in rc2 because things like that have really bad track records? Yup. That all got reverted. It fixed things for some people, but regressed for others, and we don't do that "one step forward, two steps back" thing. But never fear, we have top people looking at it.
- The crc t10 dif crypto supprt got reverted too, since there were initrd infrastructure problems with it.
- But the bulk here is some block driver updates (drbd, rsxx, xen, bcache, libata), and the drm changes (mostly qxl, but there's changes to the "big tree" too: radeon, intel, nouveau). And various random other drivers - usb, scsi, pincontrol, etc.
- There's also the usual arch updates (mainly alpha, arm, powerpc).
- Full shortlog since rc2 appended. It's big enough that I debated doing just a merge-window style "mergelog" overview, but hey, maybe people enjoy this kind of detail?
New in version 3.10 RC4 (June 3rd, 2013)
- Another week, another -rc. But this time (at least for now) only as a git tree - for people actually using the tar-balls and patches, I apologize, but I'm a complete moron, and didn't install kup, its perl dependencies, and my kup release scripts on the pixel before the trip.
- And while I can read and write email, and git is fine with just a few (flaky) kB/s internet throughput I have access to right now, installing the perl packages etc seems to be a pipe dream.
- I suspect nobody actually uses the tar-balls and patches, since git is so much more convenient and efficient, so hopefully nobody cares. But I'll rectify the lack eventually. Hopefully within a day or two, as my "yum update" actually completes. And if not in a day or two, then when I get back home a few days later.
- Anyway, rc4 is smaller than rc3 (yay!). But it could certainly be smaller still (boo!). There's the usual gaggle of driver fixes (drm, pinctrl, scsi target, fbdev, xen), but also filesystems (cifs, xfs, with small fixes to reiserfs and nfs).
- And arch updates: m68k (mostly defconfig updates), powerpc, arm and x86.
New in version 3.3 RC1 (January 20th, 2012)
- So the subject says it all. It's been two weeks(+a day), and 3.3-rc1 is now out.
- There are a couple of trees I haven't merged on purpose, and there may
- be a few trees I overlooked by mistake. The "on purpose" ones were
- things that looked unfamiliar and I felt I didn't have the bandwidth
- to check. The "mistake" ones would just be things I missed due to
- being busy.
- And it really was a pretty busy merge window. I don't know *why* it
- felt so busy, though. In pure numbers, the merge window seems to have
- been pretty normal - the number of merges and regular commits are
- right where you'd expect them. Part of it was spending what felt like
- (and I think was) a couple of days chasing down two independent
- suspend/resume regressions on my laptop, part of it was a couple of
- just bad pull requests, and some of it was some of the independent
- discussions that were on-going. But none of that is unheard of, so
- what do I know..
- Anyway, it's out now, and I'm taking off early for a weekend of beer,
- skiing and poker (not necessarily in that order: "don't drink and
- ski"). No email.
- So if you felt that your pull request was overlooked by mistake (or
- intentionally, but really not so scary that you think I should have a
- really easy time checking it), you have a couple of days to marshal
- your arguments for why I should pull it after all.
- And if you didn't send your pull request in time: "Phhhthrthtpt!". No
- arguments for that one.
- (Stats for those that like them: 20% arch updates (arm, power, mips,
- x86), 60% drivers (networking - wireless in particular, staging,
- media, dri, sound, misc - including getting rid of 'struct sysdev'),
- and 20% random stuff: filesystems, networking, perf etc)
New in version 3.0 RC2 (June 6th, 2011)
- You all know the drill by now: another week, another -rc.
- It's been reasonably quiet, although the btrfs update is bigger than I was hoping for. Other than that, it's mostly driver fixes, some ubifs updates too, and a few reverts for the early regressions.
- But -rc2 is already small enough that it easily fits as an appended shortlog, and hopefully things will stay calm. Of course, part of that may be due to other people also havin been busy traveling, so let's see (and hope for the best). And I haven't been super-eager to pull, so there is a couple of pending requests still in my mail queue.
