sched: Relax the set_cpus_allowed_ptr() semantics (2021-01-22 15:09:44 +0100)
---------------------------------------------------------------- - Correct the marking of kthreads which are supposed to run on a specific, single CPU vs such which are affine to only one CPU, mark per-cpu workqueue threads as such and make sure that marking "survives" CPU hotplug. Fix CPU hotplug issues with such kthreads.
- A fix to not push away tasks on CPUs coming online.
- Have workqueue CPU hotplug code use cpu_possible_mask when breaking affinity on CPU offlining so that pending workers can finish on newly arrived onlined CPUs too.
- Dump tasks which haven't vacated a CPU which is currently being unplugged.
- Register a special scale invariance callback which gets called on resume from RAM to read out APERF/MPERF after resume and thus make the schedutil scaling governor more precise.
---------------------------------------------------------------- Lai Jiangshan (1): workqueue: Use cpu_possible_mask instead of cpu_active_mask to break affinity
Peter Zijlstra (7): sched: Don't run cpu-online with balance_push() enabled kthread: Extract KTHREAD_IS_PER_CPU workqueue: Tag bound workers with KTHREAD_IS_PER_CPU workqueue: Restrict affinity change to rescuer sched: Prepare to use balance_push in ttwu() sched: Fix CPU hotplug / tighten is_per_cpu_kthread() sched: Relax the set_cpus_allowed_ptr() semantics
Rafael J. Wysocki (1): x86: PM: Register syscore_ops for scale invariance
Valentin Schneider (1): sched/core: Print out straggler tasks in sched_cpu_dying()
