Yes, the interface is different, and it's really not trivial to switch dm-thin
over to use it (otherwise I'd have done it already). dm-cache already uses
the new interface which could be used as a guide, especially if you look at the patches
that made the switch.
I'm going to write up some notes over the next couple of days. Which I'll post on this thread.
