Alright, my bad, turns out I had a bit too much steam on the kettle and
we cannot remove it because of the drm_sched_entity_flush() being able
to perform an asynchronous kill while the scheduler work item is still
running.
But I think we could probably put Tvrtko's flush_work() [1] here to get
the same result.
Opinions?
