xfstests results over NFS

[Jeff Layton <jlayton@kernel.org>]

I finally got my kdevops (https://github.com/linux-kdevops/kdevops) test
rig working well enough to get some publishable results. To run fstests,
kdevops will spin up a server and (in this case) 2 clients to run
xfstests' auto group. One client mounts with default options, and the
other uses NFSv3.

I tested 3 kernels:

v6.4.0 (stock release)
6.5.0-rc6-g4853c74bd7ab (Linus' tree as of a couple of days ago)
6.5.0-rc6-next-20230816-gef66bf8aeb91 (linux-next as of yesterday morning)

Here are the results summary of all 3:

With NFSv4.2, v6.4.0 has 2 extra failures that the current mainline
kernel doesn't:

    generic/193	(some sort of setattr problem)
    generic/528	(known problem with btime handling in client that has been fixed)

While I haven't investigated, I'm assuming the 193 bug is also something
that has been fixed in recent kernels. There are also 3 other NFSv3
tests that started passing since v6.4.0. I haven't looked into those.

With the linux-next kernel there are 2 new regressions:

    generic/683
    generic/684

Both of these look like problems with setuid/setgid stripping, and still
need to be investigated. I have more verbose result info on the test
failures if anyone is interested.
