Subject: [11/91] ocfs2: do not overwrite error codes in ocfs2_init_acl

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

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

From: Tiger Yang <tiger.yang@...cle.com>

commit 6eda3dd33f8a0ce58ee56a11351758643a698db4 upstream.

Setting the acl while creating a new inode depends on
the error codes of posix_acl_create_masq. This patch fix
a issue of overwriting the error codes of it.
