Hello.
Addressing your questions below.
> Can't reproduce even with putting dmcypt on raid10 after applying my
> patch.
Just a side note, that dm-crypt is not necessary here — I am able to
trigger hang with RAID10 and LVM only.
> BTW, could you share us which blk-mq scheduler you are using on sata?
Okay, now it makes sense. Previously, without your patch I was able to
reproduce the issue with "mq-deadline", "bfq" and "none". Now, I cannot
trigger it with "none" set, but "mq-deadline" still hangs for me. Does
this mean each scheduler should be modified separately?

Is it still relevant since I confirm issue to be fixed with "none"?
Thanks.
