I have a banrch with client and server support for NFSv4.2 CLONE
support:

For now you want to use btrfs on the server, as using reflinks on XFS
seems to be a little unstable over NFS.

Any reason the groups are called clone?  I don't really have an opinion
on clone vs reflink but given that the xfs_io command is reflink I'd
rather be consistent.

Otherwise I'd say get it merged ASAP, we can still fix up various
details later.
