It's already there in 4.9-rc1, although you need a special version of
xfsprogs (possibly already released, I didn't check).  It's an experimental
feature that needs to be enabled with "-m reflink=1".

Despite that experimental status, I'd strongly recommend James to test his
tool on xfs as well, as it's the second major implementation of this API[1].


Mark has already included XFS in documentation of duperemove, all that looks
amiss is btrfs-extent-same having an obsolete name.  But then, I never did
any non-superficial tests on XFS, beyond "seems to work".


Meow!

[1]. For some reasons zfs-on-linux guys didn't implement this yet, despite
it being an obvious thing on ZFS.
