In the Linux kernel, the following vulnerability has been resolved: dm rq: dont queue request to blk-mq during DM suspend DM uses blk-mqs quiesce/unquiesce to stop/start device mapper queue. But blk-mqs 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.
