Of course, that's ``just'' the kernel portion. The userland part
is arguably more difficult as I suspect you would have to fight with
inter-operating with the different bugs from each release
of each vendor's NFS code.
I don't know anything about filesystem code, I'm just curious if anyone
who has has examined whether Terry's code is worth importing. The
problem would appear, from Tery's comments above, that one would *have*
to be an expert to be able to even think about testing even just
the kernel portion. Oh, and the Last-Modified date on
