Title:
  lxc-checkconfig shows Mainline PPA Wily-4.0.7 kernel missing memory
  controller

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  net8-rmt# uname -a
  Linux ns515383.ip-167-114-159.net 4.0.7-040007-generic #201507031036 SMP Fri Jul 3 10:37:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

  net8-rmt# lxc-checkconfig | grep missing
  Cgroup memory controller: missing

  net8-rmt# grep cgroup /proc/mounts | grep memory
  cgroup /sys/fs/cgroup/memory cgroup rw,relatime,memory,release_agent=/run/cgmanager/agents/cgm-release-agent.memory 0 0

  So it appears the memory controller is available + lxc-checkconfig
  just fails to report it correctly.
