  sched_ext: Fix missing @slice and @vtime descriptions in finish_dispatch() kernel-doc (2026-08-31 07:28:04 -1000)

sched_ext: Fixes for v7.3-rc1

- The task ownership check in the dispatch queue move operation raced
  against the task exiting or moving to a different sub-scheduler,
  spuriously triggering scheduler aborts. Fix by moving the check under
  the queue lock.

- The cgroup bandwidth change callback runs in a sleepable context but
  sleepable implementations were rejected at load time. Allow them and add
  a marker so userspace can detect the capability.

- Sync tooling headers with the scx repo for accumulated compatibility
  improvements.

- Example scheduler fixes: ignored timer re-arm failures and vtime credit
  loss on cgroup migration.

- Documentation and comment fixes.
