Comment 31 for bug 1958850

in hindsight, I think the correct action for oem-5.14 would've been instead to just revert the offending commit:

345399bbc5c8a42 blk-mq: cancel blk-mq dispatch work in both blk_cleanup_queue and disk_release()

and I might still do that for the next cycle, and also revert the patchset that was added for this bug.
