Well, if the filesystem in filesystem/diskA and filesystem/diskB is the
same (multi-device) filesystem, as the above definitely implies... Tho
based on the context I don't believe that's what you actually meant.

Meanwhile, send/receive is intensely focused in bug-finding/fixing mode
ATM. The basic concept is there, but to this point it has definitely
been more development/testing-reliability (as befitted btrfs overall
state, with the eat-your-babies kconfig option warning only recently
toned down to what I'd call semi-stable) than enterprise-reliability.
Hopefully by the time they're done with all this bug-stomping it'll be
rather closer to the latter.
