I've noticed that xfstests 193 fails when run over NFS talking to an XFS-based Linux server. The test checks that we behave correctly vs Posix 1003.1 for the various operations that end up in ->setattr. Without the no_root_squash export flag we're not even able to run something resembling the test as we get permission problems all through it, see the first attachment for details. With the root_squash export op we fail to clear the setuid/setgid bits in various truncate and chown subtests, see the second attachment for details.
