From 7e48c768f44056a06bca596577c37f7721b53f0c Mon Sep 17 00:00:00 2001 From: Mike Snitzer Date: Wed, 14 Sep 2016 10:47:03 -0400 Subject: [PATCH] dm mpath: use dm_mq_kick_requeue_list() When reinstating a path the blk-mq request_queue's requeue_list should get kicked. It makes sense to kick the requeue_list as part of the existing hook (previously only used by bio-based support). Rename process_queued_bios_list to process_queued_io_list.
