Why not put the common code into fs/dmapi instead of fs/jfs/dmapi and then there will be some possibility that the XFS and JFS DMAPI implementations will become a single one (only one place to fix bugs, etc), and also give the opportunity to have DMAPI support in other filesystems? I'm sure Christoph will jump all over this (even though his name is in the code), so I thought I'd do it nicely first ;-).
