Bug description:
There are three patches that prevent possible data corruption. The
three commits are:
aef1897cd36d ("blk-mq: insert rq with DONTPREP to hctx dispatch list when
requeue")
c616cbee97ae ("blk-mq: punt failed direct issue to dispatch list")
923218f6166a ("blk-mq: don't allocate driver tag upfront for flush rq")
18.04 has all three of these patches. 16.04 has two out of the three,
but it is missing commit c616cbee97ae.
We would like to request commit c616cbee97ae be included in the 16.04 kernel:
c616cbee97ae ("blk-mq: punt failed direct issue to dispatch list")
