I can add this to my NBD queue, if desired.
If that makes life easier for you, then please be my guest -- otherwise
there's no conflict in taking it through the bitmaps tree I've got.
At this point, I'm not queuing this through NBD, as I think it is better
served by just folding this directly into your v3 permissions series (or
does that need to go up to v4?)
Just let me know either way.
