Linus,

Please pull the latest scheduler tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git sched-core-2022-12-12

# HEAD: d6962c4fe8f96f7d384d6489b6b5ab5bf3e35991 sched: Clear ttwu_pending after enqueue_task()

Scheduler changes for v6.2:

- Implement persistent user-requested affinity: introduce affinity_context::user_mask
and unconditionally preserve the user-requested CPU affinity masks, for long-lived
tasks to better interact with cpusets & CPU hotplug events over longer timespans,
without destroying the original affinity intent if the underlying topology changes.

- Uclamp updates: fix relationship between uclamp and fits_capacity()

- PSI fixes

- Misc fixes & updates.

Thanks,

Ingo
