hard to give details as i havn't used unpatched linux 2.2 nfs in a
very long time. best evidence from me is anecdotal: linux 2.4 / 2.2
nfs patches works perfectly for me (linux server, linux/irix clients,
V2 and V3), and Trond et al are very responsive if there's problem.
(eg silly delete handling bit me a couple of weeks ago, and Trond
redid it and had a patch for me within a week or so of diagnosing the
problem.).

What I remember from using unpatched linux nfs is that it was /awful/
compared to the other unixen i used, most notably in the stability
dept. As i remember it a standard linux NFS server never had much of
an uptime because of NFS. also dreadful performance to non-linux
clients.

there is a patch (well a couple -> server side and client side). The
problem is it is never integrated, so now after more than a year of
development in NFS the difference between linux nfs and /current/ NFS
is bound to be huge.

unless alan is being paid off by the commercial *nix vendors looking
to sell NFS server - no of course not. :)

not with current nfs-utils. And even if it did: show me anyone who
uses standard NFS for anything half-serious that isn't using the
patches. (either they're patching themselves or their vendor has
included the patch).

backward compat with what? we're now in the situation that the biggest
problem is that so vendors are using different revisions of the nfs
problems. none that i know of ship stock linux nfs.

even worse: we also have the situation that sometimes people submit
small patches against stock linux NFS to fix small problems that are
either fixed in the nfs patch or simply were never present in the nfs
patches.

that'd be worth discussing on the nfs list... good idea.
