Merge tag 'sched_core_for_v5.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Borislav Petkov: "Mostly minor things this time; some highlights: - core-sched: Add 'Forced Idle' accounting; this allows to track how much CPU time is 'lost' due to core scheduling constraints. - psi: Fix for MEM_FULL; a task running reclaim would be counted as a runnable task and prevent MEM_FULL from being reported. - cpuacct: Long standing fixes for some cgroup accounting issues. - rt: Bandwidth timer could, under unusual circumstances, be failed to armed, leading to indefinite throttling." [ Description above by Peter Zijlstra ] * tag 'sched_core_for_v5.17_rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: sched/fair: Replace CFS internal cpu_util() with cpu_util_cfs() sched/fair: Cleanup task_util and capacity type sched/rt: Try to restart rt period timer when rt runtime exceeded sched/fair: Document the slow path and fast path in select_task_rq_fair sched/fair: Fix per-CPU kthread and wakee stacking for asym CPU capacity sched/fair: Fix detection of per-CPU kthreads waking a task sched/cpuacct: Make user/system times in cpuacct.stat more precise sched/cpuacct: Fix user/system in shown cpuacct.usage* cpuacct: Convert BUG_ON() to WARN_ON_ONCE() cputime, cpuacct: Include guest time in user time in cpuacct.stat psi: Fix PSI_MEM_FULL state when tasks are in memstall and doing reclaim sched/core: Forced idle accounting psi: Add a missing SPDX license header psi: Remove repeated verbose comment
