Sounds good, I just wanted to make sure that you were aware of the existence
of the two. Hm, grep just notified me that we have a nfsm_uiotombuf as
well, I wonder how different THAT version is.
The NFS server could could probably profitably, and fairly easily, be taught
how to do zero-copy from the buffer/page cache, btw. Should be able to steal
code from sendfile(), although I've not looked in any detail. Possibly also
the NFS client.
