Hi Suman,

I think zvol-like functionality would be very nice for btrfs to have. It would be more natural to manage btrvols than looped-back files I think, and removing those sw layers may also increase performance, but who knows by how much. It would let btrfs really act as "just" the LVM, if desired.

Do we have any sense for how much work adding this would be?
