But I would revert:

in that order from 6.2.3 and see if that helps. Adding Yu.
Confirm the 2 Reverts fixed in my tests as well (nvme + sata drives). Nasty crash - some needed to be power cycled as they hung on shutdown.
Thank you!

Great, thanks. BTW, 6.1 is also affected. A simple reproducer is to run:
dmsetup create dev --table "0 128 zero" dmsetup remove dev
The following kconfigs are needed for the bug to be hit:
CONFIG_BLK_CGROUP=y CONFIG_BLK_DEV_THROTTLING=y CONFIG_BLK_DEV_THROTTLING_LOW=y
Sasha or Greg, can you please revert the indicated commits from 6.1 and 6.2?
Yes, will go do that right now, thanks for debugging this so quickly!
