But it didn't eliminate the call to flush_scheduled_work() that was introduced purely for the benefit of deferred device removal with commit 2c140a246dc ("dm: allow remove to be deferred"). Since DM core uses its own workqueue (and queue_work) there is no need to call flush_scheduled_work() from local_exit(). local_exit()'s destroy_workqueue(deferred_remove_workqueue) handles flushing work started with queue_work().
