I split this into two commits and cleaned them up and posted them here:

Unfortunately this doesn't work for me. When I do various filesystem
operations like git clone and a compile I see some subtle disk errors
and eventually it deadlocks, so I guess there is some problem.
OK, care to provide more details about the reproducer? Like how backend
is setup, MQ/SQ is used, disk size, ...
I have cloned linux kernel source tree on nbdublk disk and built it with
fedora 36 config for ~20min, so far so good. In my setting, backend is
'nbdkit file /dev/sda(virtio-scsi)', nbdublk is single queue.
Thanks,
Ming
