I see where you are coming from, but the {"stock 2.4","2.2 patch"} NFS
code is well tested, lots of bug fixes for NFSv2 and the 'new' code ->
NFSv3 client/server is a compile yes/no option, just like the USB
backport.
2.2 without patches - NFS has performance/reliability problems
2.2 with patches - NFSv2 provided with lots of bugfixes
NFSv3 is compile time optional

I have not heard of anyone that prefers stock 2.2 NFS over
patched/2.4. Anecdotal evidence[1] suggests:

- stock 2.2 has 'issues' with NFS, serving in particular. Bad enough
that linux users would consider switching to another *nix for NFS
serving.

- 2.2 + NFS patches does not have issues (or very few), and would even
appear to work quite well, definitely for NFSv2 and seemingly for
the optional v3[2]. Certainly you need the patches for
interoperability.

- all the NFS developers are working the 2.4 code and backporting to
2.2. So issues wrt to the current 2.2 NFS codebase will not get
fixed. Issues wrt to the 2.4 backport do get fixed.

So the anecdotal evidence suggests we don't have anything to lose but
a not very good NFS server, and everything to gain.

What are the issues with updating NFS code that do not exist with
other drivers, filesystems, etc... in 2.2 for which updates are
accepted?

what is there to lose?

[1]. as gathered from posts to this thread, to the nfs sourceforge
lists and my experience of stock NFS as of over a year ago and the NFS
patches since then.

[2]. linux v3 works flawlessly against IRIX 6.2 + ONC3 updates, both
as client and server, for me.
