You're probably best from a DAX implementation POV to head down the GFS2 path, as FS-DAX requires the filesystem to use the fs/iomap/ extent mapping implementation. GFS2 is already partially ported to use the iomap infrastructure, though more work is needed to provide the iomap functionality DAX requires. OCFS2 would require a lot more work on this front....
