Add a patch to fix Intel E100 wake-on-lan problems.

[people/pmueller/ipfire-2.x.git] / src / patches / suse-2.6.27.31 / patches.apparmor / do_path_lookup-nameidata.diff

From: Andreas Gruenbacher <agruen@suse.de>
Subject: Switch to vfs_permission() in do_path_lookup()

Switch from file_permission() to vfs_permission() in do_path_lookup():
this avoids calling permission() with a NULL nameidata here.
