As far as I remember that text we have had a number in request

bitmap at a time.

Would this work for you?
I think that would be much better, yes, though I'd suggest the
bitmap had an ID other than a number 0..15 so other people
can use it too.

bitmap requires to negotiate granularity which is
not that easy thing.

If we have different granularities for 'dirty' and 'allocated'
bitmaps and we can report this using this proto and
can not do this cleanly with bitmap approach assuming
that we will add 'NBD_STATE_DIRTY_DEALLOCATED' (0x2) state
