That shouldn't be run by default; see patch, appended.

I suspect the server's actually OK here, but I need to look more
closely.

For what it's worth, this is what I do as part of my regular regression
tests, for 4.0:

	http://git.linux-nfs.org/?p=bfields/testd.git;a=blob;f=bin/do-pynfs;h=4ed0f7942b9ff0907cbd3bb0ec1643dad02758f5;hb=HEAD

and for 4.1:

	http://git.linux-nfs.org/?p=bfields/testd.git;a=blob;f=bin/do-pynfs41;h=b3afc60dfab17aa5037d3f587d3d113bc772970e;hb=HEAD

There are some known 4.0 failures that I skip:

(But LOCK24 isn't on that list because I keep saying I'm going to triage
it....)

And for 4.1:
	http://git.linux-nfs.org/?p=bfields/testd.git;a=blob;f=data/pynfs41-skip;h=c682bed97742cf799b94364872c7575ac9fc188c;hb=HEAD

commit 98f4ce2e6418
Author: J. Bruce Fields <bfields@redhat.com>
Date:   Tue Jun 1 11:10:06 2021 -0400

    nfs4.0 secinfo: auth_gss not required
    
    RPCSEC_GSS is mandatory to implement, but that doesn't mean every server
    will have it be configured on.
    
    I try to only add the "all" tag to tests whose failure indicates the
    server is really out of spec, or at least is very unusual and likely to
    cause problems for clients.
