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,
