Title:
  cgroup namespace update

Status in linux package in Ubuntu:
  Triaged
Status in linux source package in Xenial:
  Fix Committed

Bug description:
   During xenial cycle we applied a patch (and a followon fix for criu)
  to fix a usability problem with cgroup namespaces and /proc/self/mountinfo.
  Since then, the approach to fix it upstream has changed.  Please revert
  the two nsroot patches currently in xenial and yakkety, and replace them
  with the new patches.

  Impact:
  One or the other of these patchsets suffices for docker in lxd to work.
  The patchset being reverted required a docker patch, the new one does
  not.  Docker cannot work inside lxd with neither patchset.
