Merge tag 'sched-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull scheduler updates from Ingo Molnar: - Clean up SCHED_DEBUG: move the decades old mess of sysctl, procfs and debugfs interfaces to a unified debugfs interface. - Signals: Allow caching one sigqueue object per task, to improve performance & latencies. - Improve newidle_balance() irq-off latencies on systems with a large number of CPU cgroups. - Improve energy-aware scheduling - Improve the PELT metrics for certain workloads - Reintroduce select_idle_smt() to improve load-balancing locality - but without the previous regressions - Add 'scheduler latency debugging': warn after long periods of pending need_resched. This is an opt-in feature that requires the enabling of the LATENCY_WARN scheduler feature, or the use of the resched_latency_warn_ms=xx boot parameter. - CPU hotplug fixes for HP-rollback, and for the 'fail' interface. Fix remaining balance_push() vs. hotplug holes/races - PSI fixes, plus allow /proc/pressure/ files to be written by CAP_SYS_RESOURCE tasks as well - Fix/improve various load-balancing corner cases vs. capacity margins - Fix sched topology on systems with NUMA diameter of 3 or above - Fix PF_KTHREAD vs to_kthread() race - Minor rseq optimizations - Misc cleanups, optimizations, fixes and smaller updates * tag 'sched-core-2021-04-28' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (61 commits) cpumask/hotplug: Fix cpu_dying() state tracking kthread: Fix PF_KTHREAD vs to_kthread() race sched/debug: Fix cgroup_path[] serialization sched,psi: Handle potential task count underflow bugs more gracefully sched: Warn on long periods of pending need_resched sched/fair: Move update_nohz_stats() to the CONFIG_NO_HZ_COMMON block to simplify the code & fix an unused function warning sched/debug: Rename the sched_debug parameter to sched_verbose sched,fair: Alternative sched_slice() sched: Move /proc/sched_debug to debugfs sched,debug: Convert sysctl sched_domains to debugfs debugfs: Implement debugfs_create_str() sched,preempt: Move preempt_dynamic to debug.c sched: Move SCHED_DEBUG sysctl to debugfs sched: Don't make LATENCYTOP select SCHED_DEBUG sched: Remove sched_schedstats sysctl out from under SCHED_DEBUG sched/numa: Allow runtime enabling/disabling of NUMA balance without SCHED_DEBUG sched: Use cpu_dying() to fix balance_push vs hotplug-rollback cpumask: Introduce DYING mask cpumask: Make cpu_{online,possible,present,active}() inline rseq: Optimise rseq_get_rseq_cs() and clear_rseq_cs() ...
