Yes, that is because of the following line: q->bio_split = bioset_create(BIO_POOL_SIZE, 0); in blk_alloc_queue_node(). Looks like this bio_set doesn't need to be per-request_queue, and now it is only used for fast-cloning bio for splitting, and one global split bio_set should be enough. thanks, Ming
