dm: fix request-based DM to not bounce through indirect dm_submit_bio
It is unnecessary to force request-based DM to call into bio-based dm_submit_bio (via indirect disk->fops->submit_bio) only to have it then call blk_mq_submit_bio(). Fix this by establishing a request-based DM block_device_operations (dm_rq_blk_dops, which doesn't have .submit_bio) and update dm_setup_md_queue() to set md->disk->fops to it for DM_TYPE_REQUEST_BASED. Remove DM_TYPE_REQUEST_BASED conditional in dm_submit_bio and unexport blk_mq_submit_bio. Fixes: c62b37d96b6eb ("block: move ->make_request_fn to struct block_device_operations") Signed-off-by: Mike Snitzer <snitzer@redhat.com>
