The loop driver wants to synchronously perform autoclear operation, for some userspace programs (e.g. xfstest) depend on that the autoclear operation already completes by the moment lo_release() from close() returns to userspace and immediately call umount() of a partition containing a backing file which the autoclear operation will close(). Export task_work_add() so that the loop driver can perform autoclear operation by the moment lo_release() from close() returns to userspace.
