Well, it's two different things. My prime concern right now is
null_blk, which is very clumsy due to the two different I/O paths,
and actually broken in that the bio mode doesn't respect various
I/O limits that can be configured, and at least in zone modes also
ones that aren't configured but required (I/Os spanning zones).
