In the Linux kernel, the following vulnerability has been resolved:
dm rq: don’t queue request to blk-mq during DM suspend
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.
