Subject: [GIT PULL v2] nohz: Posix cpu timers handling on full dynticks
Date: Fri, 19 Apr 2013 16:51:37 +0200	[thread overview]
Message-ID: <1366383100-17053-1-git-send-email-fweisbec@gmail.com> (raw)

Ingo,

Please pull this second version of the dynticks handling of posix cpu
timers from:

git://git.kernel.org/pub/scm/linux/kernel/git/frederic/linux-dynticks.git
	timers/nohz-posix-timers-v2

This fixes an issue with a race between run_posix_cpu_timers() and full
dynticks CPUs that we found while discussing a patch with Olivier Langlois.

As a bonus, it also provides the other side of posix cpu timers handling
in dynticks with the new helper to check before stopping the tick.

Thanks.

Frederic Weisbecker (3):
  nohz: New APIs to re-evaluate the tick on full dynticks CPUs
  posix_timers: Kick full dynticks CPUs when a posix cpu timer is armed
  posix_timers: New API to prevent from stopping the tick when timers
    are running
