This patch exports blk_register_queue(). blk_register_queue() is called through add_disk(). Request-based dm defers queue allocation/initialization until a mapping table is loaded, since the way to initialize queue is different between bio-based mapping and request-based mapping. So request-based dm needs to call add_disk() and blk_register_queue() separately.
