Subject: [GIT PULL] scheduler fixes
Date: Fri, 31 Oct 2014 12:17:51 +0100 [thread overview]
Message-ID: <20141031111751.GA28586@gmail.com> (raw)
Linus,
Please pull the latest sched-urgent-for-linus git tree from:

# HEAD: f3a7e1a9c464a32ee186ab91388313c82e7ce018 sched/dl: Fix preemption checks
Various scheduler fixes all over the place: three SCHED_DL fixes,
three sched/numa fixes, two generic race fixes and a comment fix.
Thanks,
Ingo
------------------>
Chen Hanxiao (1):
sched: Update comments for CLONE_NEWNS
Juri Lelli (2):
sched/deadline: Don't replenish from a !SCHED_DEADLINE entity
sched/deadline: Fix races between rt_mutex_setprio() and dl_task_timer()
Kirill Tkhai (4):
sched: Fix race between task_group and sched_task_group
sched/numa: Fix unsafe get_task_struct() in task_numa_assign()
sched/fair: Fix division by zero sysctl_numa_balancing_scan_size
sched/dl: Fix preemption checks
Oleg Nesterov (1):
sched: stop the unbound recursion in preempt_schedule_context()
Yasuaki Ishimatsu (1):
sched/fair: Care divide error in update_task_scan_period()
