Subject: dm: always call blk_queue_split() in dm_process_bio()
X-Git-Tag: v5.15~6824^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=effd58c95f277744f75d6e08819ac859dbcbd351;p=platform%2Fkernel%2Flinux-starfive.git

dm: always call blk_queue_split() in dm_process_bio()

Do not just call blk_queue_split() if the bio is_abnormal_io().

Fixes: 568c73a355e ("dm: update dm_process_bio() to split bio if in ->make_request_fn()")
