Subject: [AppArmor 39/47] Fix file_permission()
Date: Thu, 20 Dec 2007 06:09:49 -0800 [thread overview]
Message-ID: <20071220140947.312934105@suse.de> (raw)
In-Reply-To: 20071220140910.934607826@suse.de
[-- Attachment #1: file_permission-nameidata.diff --]
[-- Type: text/plain, Size: 759 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.
