[dm-devel] [RFC PATCH 04/13] block: export blk_register_queue

[Kiyoshi Ueda <k-ueda ct jp nec com>]

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.
