Compcache 0.6.2 - Changelog

What's new in Compcache 0.6.2:

January 29th, 2010

· Sync-up with mainline version which includes changes below.
· Lots and lots of cleanups.
· Use small case for ramzswap module parameter: NUM_DEVICES -> num_devices.
· Add three module parameters: backing_swap, memlimit_kb and disksize_kb to allow initializing the first device (/dev/ramzswap0) without using rzscontrol utility (see Issue #50).
· Use 'struct page' instead of 32-bit PFNs in ramzswap driver and xvmalloc. This is to make these 64-bit safe.
· xvmalloc is no longer a separate module and does not export any symbols. Its compiled directly with ramzswap block driver.
· Removed useless {load,unload}_modules.sh scripts.
· Fix to make sure disksize matches usable pages in backing swap file.
· Fix memory leak in (rare) error condition in init_device().
· Fix memory leak in (rare) failure in create_device().
· Remove swap discard hooks. Swap notifiers makes these redundant.
· Unify init_device() fail path and reset_device().
· Do not accept backing swap with bad pages.
· Fix zero-page accounting.
· Use lock for 64-bit stats to prevent value corruption.
· Rewrite swap notify patch.
· Fix crash when reset is called when there are pending I/Os.
