From fd55f9f292617c7475c62c07ed6c478b4bd9eda5 Mon Sep 17 00:00:00 2001

Subject: [PATCH] policy/modules/kernel/files: 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 [embedded specific]
