Merge tag 'sched_ext-for-6.19-rc8-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext fix from Tejun Heo:

 - Fix race where sched_class operations (sched_setscheduler() and
   friends) could be invoked on dead tasks after sched_ext_dead()
   already ran, causing invalid SCX task state transitions and NULL
   pointer dereferences.

   This was a regression from the cgroup exit ordering fix which
   moved sched_ext_free() to finish_task_switch().
