Subject: [GIT PULL] scheduler changes for v4.17
Linus,
Please pull the latest sched-core-for-linus git tree from:
git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-for-linus
# HEAD: b720342849fe685310fca01748a32730a6eca5aa sched/core: Update preempt_notifier_key to modern API
The main scheduler changes in this cycle were:
- NUMA balancing improvements (Mel Gorman)
- Further load tracking improvements (Patrick Bellasi)
- Various NOHZ balancing cleanups and
optimizations (Peter Zijlstra)
- Improve blocked load handling, in particular we can now reduce
and eventually stop periodic load updates on 'very idle' CPUs.
(Vincent Guittot)
- On isolated CPUs offload the final 1Hz scheduler tick as well,
plus related cleanups and reorganization.
(Frederic Weisbecker)
- Core scheduler code cleanups (Ingo Molnar)
Thanks,
Ingo
