[PATCH 3.12 067/116] NFS: Fix a missing initialisation when reading the SELinux label

From: Greg Kroah-Hartman
Date: Tue Nov 26 2013 - 20:23:18 EST


3.12-stable review patch. If anyone has any objections, please let me know.

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

From: Trond Myklebust <Trond.Myklebust@xxxxxxxxxx>

commit fcb63a9bd8427fc584229048ea14f1453dc9a2e1 upstream.

Ensure that _nfs4_do_get_security_label() also initialises the
SEQUENCE call correctly, by having it call into nfs4_call_sync().
