[PATCH] bug: nfsd/nfs4xdr.c misuse of ERR_PTR()
a) ERR_PTR(nfserr_something) is a bad idea;
IS_ERR() will be false for it.
b) mixing nfserr_.... with -EOPNOTSUPP is
even worse idea.
nfsd4_path() does both; caller expects to get NFS protocol error out it if
anything goes wrong, but if it does we either do not notice (see (a)) or get
host-endian negative (see (b)).
IOW, that's a case when we can't use ERR_PTR() to return error, even though we
return a pointer in case of success.
