Linus Torvalds f7574d3f90 sched_ext: Fixes for v7.2-rc3
- Lifecycle fixes for the new sub-scheduler support: two use-after-frees
   and an enable-failure path that left a half-initialized sub-scheduler
   linked.
 
 - Two dispatch-path locking bugs: a spurious scheduler abort from a
   migration race, and a lockdep splat from stale runqueue-lock tracking.
 
 - Callback and task-state fixes: stale scheduler-owned state on a task
   leaving SCX, a weight callback running after disable, and a bogus
   warning on core-scheduling forced idle.
 
 - On nohz_full, finite-slice tasks could miss the tick that expires their
   slice. Enable it when such a task is picked, with a selftest.
 
 - Smaller fixes: userspace CPU-mask helpers, ratelimited deprecation
   warnings, docs and a sparse annotation.
