All these made a whole lot more sense before Darrick reshuffled the code. In my original version I started massaging the XFS code so that it can be moved to iomap without functional changes, but Darrick wanted the iomap code added in one series and then XFS switched over, which made a lot of things more confusing than they were intended to be.
