Merge tag 'sched_ext-for-7.3-rc4-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_extHEADmaster

Pull sched_ext fixes from Tejun Heo:

 - A task reenqueued while its dispatch was still completing had its
   queued state clobbered by the dispatcher, dropping every later
   dispatch of the task. Wait for the in-flight dispatch to settle
   first

 - A wakeup activation on another CPU marked the destination runqueue as
   mid-wakeup, stranding a pending local reenqueue. If the scheduler was
   unloaded first, the stale request pointed into freed memory that the
   next scheduler dereferenced

 - ops.dequeue() ran with the source dispatch queue's lock held, so a
   scheduler iterating that queue from the callback deadlocked the CPU

 - Schedulers with their own CPU ID mapping had no way to learn a task's
   initial CPU mask and rebuilt it themselves, which went wrong across
   sub-scheduler enable and re-home. Pass it to ops.enable()

 - A bypass dispatch event counter missed the dispatches made by the
   end-of-dispatch fallback and under-reported

 - Selftests for the dequeue locking and initial mask changes
