Title:
  [Regression] Unprivileged containers fail to start in linux-lts-utopic

Status in linux-lts-utopic package in Ubuntu:
  Fix Released

Bug description:
  == SRU Justification ==

  Impact: linux-lts-utopic 3.16.0-46.62 contains a regression which
  prevents unprivileged containers from starting due to a failure
  mounting sysfs.

  Fix: Backport of upstream commit
  f9bb48825a6b5d02f4cabcc78967c75db903dcdc, which is marked for stable
  but is missing from 3.16 stable. Another stable commit that did get
  into 3.16 requires this patch.

  Regression potential: This patch is specifically targeted at
  unprivileged mounts of virtual filesystems in containers and fixes a
  regression there. It should have no impact on mounts in the host.

  ---

  linux-lts-utopic 3.16.0-46.62 contains a regression mounting
  unprivileged containers. The log shows a failure mounting sysfs:

        lxc-start 20150427012246.807 ERROR    lxc_conf -
  conf.c:lxc_mount_auto_mounts:819 - Operation not permitted - error
  mounting sysfs on /usr/lib/x86_64-linux-gnu/lxc/sys flags 14

  This is due to missing upstream commit
  f9bb48825a6b5d02f4cabcc78967c75db903dcdc.
