one outstanding command on a queue at any given time.
- blk_queue_init_tags(request_queue_t *q, int depth)
+ blk_queue_init_tags(struct request_queue *q, int depth)
Initialize internal command tagging structures for a maximum
depth of 'depth'.
- blk_queue_free_tags((request_queue_t *q)

Teardown tag info associated with the queue. This will be done
automatically by block if blk_queue_cleanup() is called on a queue
The above are initialization and exit management, the main helpers during
normal operations are:
- blk_queue_start_tag(request_queue_t *q, struct request *rq)
+ blk_queue_start_tag(struct request_queue *q, struct request *rq)
Start tagged operation for this request. A free tag number between
0 and 'depth' is assigned to the request (rq->tag holds this number),
for this queue is already achieved (or if the tag wasn't started for
some other reason), 1 is returned. Otherwise 0 is returned.
- blk_queue_end_tag(request_queue_t *q, struct request *rq)
+ blk_queue_end_tag(struct request_queue *q, struct request *rq)
End tagged operation on this request. 'rq' is removed from the internal
book keeping structures.

all the outstanding requests. There's a third helper to do that:
- blk_queue_invalidate_tags(request_queue_t *q)

to the request queue. The driver will receive them again on the
