Revision b4459b11e84092658fa195a2587aff3b9637f0e7 authored by Ming Lei on 23 September 2021, 09:11:31 UTC, committed by Mike Snitzer on 12 October 2021, 17:54:10 UTC
DM uses blk-mq's quiesce/unquiesce to stop/start device mapper queue. But blk-mq's unquiesce may come from outside events, such as elevator switch, updating nr_requests or others, and request may come during suspend, so simply ask for blk-mq to requeue it. Fixes one kernel panic issue when running updating nr_requests and dm-mpath suspend/resume stress test.
