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....
Cheers,
Dave.
