"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." - said Linus Torvalds in the announcement.
