I only see this

@amshinde , @devimc, the limitation is mentioned in the mkfs.xfs manual page: http://man7.org/linux/man-pages/man8/mkfs.xfs.8.html

                          Note: the filesystem DAX mount option ( -o dax )
                          is incompatible with reflink-enabled XFS
                          filesystems.  To use filesystem DAX with XFS,
                          specify the -m reflink=0 option to mkfs.xfs to
                          disable the reflink feature.
