Subject: [PATCH 3.11 243/272] nfsd4: fix discarded security labels on setattr
3.11.10.1 -stable review patch. If anyone has any objections, please let me know.
------------------
From: "J. Bruce Fields" <bfields@...hat.com>
commit 3378b7f40d79930f0f447a164c7e8fcbe4480e40 upstream.
Security labels in setattr calls are currently ignored because we forget
to set label->len.
