In drm_sched_fini() all entities are marked as stopped - without taking the appropriate lock, because that would deadlock. That means that drm_sched_fini() and drm_sched_entity_push_job() can race against each other. This should most likely be fixed by establishing the rule that all entities associated with a scheduler must be torn down first. Then, however, the locking should be removed from drm_sched_fini() alltogether with an appropriate comment.
