Yes, the 4.1 client side (including pNFS support for File Layouts only)
is in 10.0. There is server code in projects/nfsv4.1-server, but it does
not include pNFS (and I don't plan on trying to do pNFS support, since
it is a major project). The main piece missing from the NFSv4.1 server
is backchannel support (for callbacks) in sessions and I am currently
working on that.
