blk-mq: only allocate a single mq_map per tag_set
The mapping is identical for all queues in a tag_set, so stop wasting memory for building multiple. Note that for now I've kept the mq_map pointer in the request_queue, but we'll need to investigate if we can remove it without suffering too much from the additional pointer chasing. The same would apply to the mq_ops pointer as well. Signed-off-by: Christoph Hellwig <> Reviewed-by: Keith Busch <> Signed-off-by: Jens Axboe <>
