From fbba8d89acea5d628d1d076b1d8962db438ff832 Mon Sep 17 00:00:00 2001 From: John Johansen Date: Thu, 16 Feb 2012 06:28:50 -0800 Subject: AppArmor: Retrieve the dentry_path for error reporting when path lookup fails When __d_path and d_absolute_path fail due to the name being outside of the current namespace no name is reported. Use dentry_path to provide some hint as to which file was being accessed.
