Linux 3.3-rc1 Released, Merge Window Closes

Linus Torvalds released the Linux 3.3-rc1 kernel on Thursday afternoon that marks the closure of the two-week Linux 3.3 kernel merge window.

From the release announcement:
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)

Among the pulls that Linus handled in the 3.3 kernel prior to his beer-fueled weekend include:

- Many DRM changes affecting all of the leading open-source graphics drivers.

- Linaro's DMA-BUF and Radeon VM.

- BQL for fighting Bufferbloat.

- EXT4 file-system improvements as well as Btrfs enhancements.

- Better ACPI / power management support, including fixing the most notorious Linux kernel power regression.

These are just some of the exciting changes found in Linux 3.3. Expect more coverage on Phoronix once SCALE 10x is over.
