Add ignored *.diff files of the xen patches
[ipfire-2.x.git] / src / patches / suse-2.6.27.39 / patches.apparmor / vfs-notify_change.diff
1 From: Tony Jones <tonyj@suse.de>
2 Subject: Add a vfsmount parameter to notify_change()
3
4 The vfsmount parameter must be set appropriately for files visibile
5 outside the kernel. Files that are only used in a filesystem (e.g.,
6 reiserfs xattr files) will have a NULL vfsmount.
