Oh, also, not included: server-to-server copy offload.  I think it's
more or less ready, but due to some miscommunication (at least partly my
fault), I didn't get them in my nfsd-next branch till this week.  And
the client side (which it builds on) isn't merged yet last I checked.
So, it seemed more prudent to back them out and wait till next time.
