Ingo, Thomas,
Please pull the timers/posix-timers-for-tip branch that can be found at:
git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git timers/posix-timers-for-tip
HEAD: 239dd62b5c41bf606f3a3b3adb9e70341a62dbd3 It passed through 0-day testing.
This is another series of posix cpu timers cleanups. Note it's essentially the same as: "posix-timers: Various cleanups" at http://lkml.org/lkml/2013/10/12/107 which Peter Zijlstra had a look into. He told me that it looked ok. This version brings almost no code change (just fix a NULL check ommitted somewhere), it's mostly a rebase against 2.6.12 with refined changelogs.
It's a first pile but more is to come, as I have some more cleanups in mind. Plus I plan to integrate more fixes from Kosaki Motohiro.
Changes:
* Remove a few irrelevant optimizations that were complicating the code a lot * Consolidate local and remote clock read * Remove dead leftovers * Optimize the locking by removing unnecessary uses of tasklist lock * Various other cleanups...
Thanks, Frederic ---
