Subject: [PATCH] blk-mq: rename blk_attempt_bio_merge
Git-commit: b131f2011115f3c18a49e17762486501496fea3c
Patch-mainline: v5.16-rc1
References: jsc#PED-1183
It is very annoying to have two block layer functions which share same
name, so rename blk_attempt_bio_merge in blk-mq.c as
blk_mq_attempt_bio_merge.
