dm: fix comment in dm_process_bio() (cf9c3786) · Commits · 戴 / test

Refer to the correct function (->submit_bio instead of ->queue_bio). Also, add details about why using blk_queue_split() isn't needed for dm_wq_work()'s call to dm_process_bio(). Fixes: ("block: move ->make_request_fn to struct block_device_operations") Signed-off-by:
