Subject: How is the progress for removing flush_scheduled_work() callers?

Like commit c4f135d643823a86 ("workqueue: Wrap flush_workqueue() using a
macro") says, flush_scheduled_work() is dangerous and will be forbidden.
We are on the way for removing all flush_scheduled_work() callers from
the kernel, and there are only 4 callers remaining as of linux-20221104.

  drivers/gpu/drm/i915/display/intel_display.c:8997:      flush_scheduled_work();
  drivers/gpu/drm/i915/gt/selftest_execlists.c:88:        flush_scheduled_work();
  drivers/md/dm.c:234:    flush_scheduled_work();
  drivers/message/fusion/mptscsih.c:1234: flush_scheduled_work();

I'm planning to start emitting runtime messages in linux-next.git tree.
