    Oh now elevator_exit() has been moved into blk_release_queue(). But
    problem will still be there, isn't it? During driver init, most likely driver
    is holding last reference of the queue and blk_release_queue() will be called
    in the context of blk_cleanup_queue() causing the overhead?
