3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Richard Cochran <richardcoch...@gmail.com>
commit 88391d49abb7d8dee91d405f96bd9e003cb6798d upstream.
The hash values 0 and 1 are reserved for magic directory entries, but
the code only prevents names hashing to 0. This patch fixes the test
to also prevent hash value 1.
