Outside of the graphs realm, the Linux 2.6.33 kernel brings CFQ scheduler improvements, new drivers, and other key enhancements. The performance of the Linux 2.6.33 kernel can be monitored on a daily basis through Phoromatic Tracker that just launched from our test farm this week.
Below is the Linux 2.6.33-rc1 kernel release announcement. Going forward with the Linux 2.6.34 kernel and future releases, Linus is looking at making the merge window a few days shorter (11~12 days as opposed to 14) to prevent developers from issuing pull requests so late into the new development cycle.
So the merge window is closed, and -rc1 is out there now.
Talking about the merge window: there were a _lot_ of trees that left their pull requests pretty dang late. Not everything I merged yesterday and today were late pull requests, but a lot of it was. I'm used to have a fairly busy last day of the merge window, but it was a busy last two days this time - definitely worse than usual.
The two-week merge window is _not_ supposed to be "one day merge window after thirteen days of silence". In fact, I think that next time around I'll make the merge window be 11-12 days instead, and people who try to game the system and do a last-minute pull request will get a surprise, and get unceremoniously bumped to 2.6.35 instead.
Anyway, apart from that grumbling, it's been a fairly normal merge window, I think. According to git dirstat (which got fixed to give more accurate numbers), the distribution of changes is pretty much
- 1/3rd staging
- 1/3rd "rest of drivers"
- 1/3rd "everything else"
with about half of that final "everything else" third being arch stuff, and half being random other things (firmware, fs, net).
Notable additions? There's a number of drivers, and depending on which ones you use, you'll find them more or less notable. I personally like how I finally got to merge the Nouveau code, for example. Others will care about other things.
Please give it a good testing, so that we can start figuring out the inevitably regressions,
