Merge tag 'sched_ext-for-7.3-rc7-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/sched_ext

Pull sched_ext fixes from Tejun Heo:

 - A task that skipped the BPF scheduler on its way back to its CPU's
   local queue could stall there until the watchdog fired, as the CPU
   had already decided to go idle.

 - Use-after-free of a destroyed user dispatch queue by a deferred
   re-enqueue request.

 - A task could be moved off a dispatch queue while the dispatching CPU
   was still running ops.dequeue() on it.

 - Bypass mode mishandled a sub-scheduler bypass overlapping an
   ancestor's, as across a system suspend. Descendants could leave
   bypass mid-teardown and tasks could be stranded on bypass queues.

 - The idle CPU selection helper could return a CPU outside the allowed
   CPUs of a pinned or migration-disabled task.
