Subject[PATCH 3.4 18/43] nfsd4: fix test_stateid error reply encoding
Date
3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: "J. Bruce Fields" <bfields@redhat.com>

commit a11fcce1544df08c723d950ff0edef3adac40405 upstream.

If the entire operation fails then there's nothing to encode.
