+Subject: [PATCH] LXC: Don't mount securityfs when user namespace enabled
+
+commit 1583dfda7c4e5ad71efe0615c06e5676528d8203 from
+git://libvirt.org/libvirt.git
+
+Right now, securityfs is disallowed to be mounted in non-initial
+user namespace, so we must avoid trying to mount securityfs in
+a container which has user namespace enabled.
