32 * NFS stats. The good thing with these values is that NFSv3 errors are
33 * a superset of NFSv2 errors (with the exception of NFSERR_WFLUSH which
34 * no-one uses anyway), so we can happily mix code as long as we make sure
35 * no NFSv3 errors are returned to NFSv2 clients.
36 * Error codes that have a `--' in the v2 column are not part of the
37 * standard, but seem to be widely used nevertheless.
