Subject: [AppArmor 45/45] Fix file_permission()
Date: Thu, 25 Oct 2007 23:41:09 -0700	[thread overview]
Message-ID: <20071026064053.233728624@suse.de> (raw)
In-Reply-To: 20071026064024.243943043@suse.de

[-- Attachment #1: file_permission-nameidata.diff --]
[-- Type: text/plain, Size: 744 bytes --]

We cannot easily switch from file_permission() to vfs_permission()
everywhere, so fix file_permission() to not use a NULL nameidata
for the remaining users.
