Your next homework assignment might be btrfs:

There are plenty of good concepts out there and VSI may have some new
ones of its own up its sleeve. It will be no small feat to make
something really tuned in to the storage of today and tomorrow but also
backward compatible with (most of) the older interfaces and
applications. But the payoff could be significant. Maybe we can replace
BACKUP/IGNORE=INTERLOCK with BACKUP/TAKE_SNAPSHOT or something.
