Subject: [104/111] ocfs2: Set MS_POSIXACL on remount

2.6.32-stable review patch.  If anyone has any objections, please let us know.

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

From: Jan Kara <jack@...e.cz>

commit 57b09bb5e492c37c1e4273fe4e435ffd1d2ddbe0 upstream.

We have to set MS_POSIXACL on remount as well. Otherwise VFS
would not know we started supporting ACLs after remount and
thus ACLs would not work.
