I'm not going to have time to do much review or testing of the DAX
changes (apart from the cursor comments I've already made) because
of the huge pile of XFS reflink changes I've got ot get through
first. However, I've already got the iomap dax bits in the XFS tree
so I can pull everything through there if review and testing is
covered otherwise......

Cheers,

Dave.
