Revision 81ea1222f2fa5006f4b9759c2fe1ec154109622d authored by Ming Lei on 20 April 2023, 11:20:18 UTC, committed by Jens Axboe on 20 April 2023, 12:54:17 UTC
This reverts commit 23f3e3272e7a4d9fb870485cd6df1e4f9539282c.
blk-mq sched bio merge still needs request to grab queue usage counter,
so we can't simply call blk_mq_attempt_bio_merge() when queue usage
counter isn't held.
Fixes: 23f3e3272e7a ("block: Merge bio before checking ->cached_rq")
