From 22cd030a8118faae37c0835eb7875e482efe5dc1 Mon Sep 17 00:00:00 2001
From: Xin Ouyang <Xin.Ouyang@windriver.com>

Subject: [PATCH] add rules for the symlink of /tmp

/tmp is a symlink in poky, so we need allow rules for files to read
lnk_file while doing search/list/delete/rw.. in /tmp/ directory.

Upstream-Status: Inappropriate [only for Poky]
