OK, the QUEUE_FLAG_DEAD. I assume that will be set in blk_cleanup_queue?
Then all remaining requests are flushed out of the queue?
This requires that a driver must be able to continue to process requests
during the call to blk_cleanup_queue, and that blk_cleanup_queue might
block, right? Is this acceptable, or should there be an earlier call to
set QUEUE_FLAG_DEAD and ensure queue is flushed?
