Merge branch 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: "The biggest changes in this cycle were: - Make kcpustat vtime aware (Frederic Weisbecker) - Rework the CFS load_balance() logic (Vincent Guittot) - Misc cleanups, smaller enhancements, fixes. The load-balancing rework is the most intrusive change: it replaces the old heuristics that have become less meaningful after the introduction of the PELT metrics, with a grounds-up load-balancing algorithm. As such it's not really an iterative series, but replaces the old load-balancing logic with the new one. We hope there are no performance regressions left - but statistically it's highly probable that there *is* going to be some workload that is hurting from these chnages. If so then we'd prefer to have a look at that workload and fix its scheduling, instead of reverting the changes" * 'sched-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (46 commits) rackmeter: Use vtime aware kcpustat accessor leds: Use all-in-one vtime aware kcpustat accessor cpufreq: Use vtime aware kcpustat accessors for user time procfs: Use all-in-one vtime aware kcpustat accessor sched/vtime: Bring up complete kcpustat accessor sched/cputime: Support other fields on kcpustat_field() sched/cpufreq: Move the cfs_rq_util_change() call to cpufreq_update_util() sched/fair: Add comments for group_type and balancing at SD_NUMA level sched/fair: Fix rework of find_idlest_group() sched/uclamp: Fix overzealous type replacement sched/Kconfig: Fix spelling mistake in user-visible help text sched/core: Further clarify sched_class::set_next_task() sched/fair: Use mul_u32_u32() sched/core: Simplify sched_class::pick_next_task() sched/core: Optimize pick_next_task() sched/core: Make pick_next_task_idle() more consistent sched/fair: Better document newidle_balance() leds: Use vtime aware kcpustat accessor to fetch CPUTIME_SYSTEM cpufreq: Use vtime aware kcpustat accessor to fetch CPUTIME_SYSTEM procfs: Use vtime aware kcpustat accessor to fetch CPUTIME_SYSTEM ...
