Title:
  unprivileged overlayfs mounts no longer work in utopic

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  In 3.13.0-33-generic, root in a non-init user namespace can do
  overlayfs mounts.  In 3.16.0-5-generic he cannot.

  Test case:

  sudo apt-get install lxc
  lxc-usernsexec  -- /bin/bash    # start a containerized root shell
  #  mkdir /tmp/a /tmp/b /tmp/c
  # mount -t overlayfs -o upperdir=/tmp/a,lowerdir=/tmp/b x /tmp/c

  This works in trusty, but not in latest utopic.

  (A testcase for this will be added to the lxc-tests package, but isn't
  there yet)
