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
