Title:
  anon_inode:[eventfd] leaked on vgs invocation inside lxd container

Status in lvm2 package in Ubuntu:
  Invalid
Status in lxd package in Ubuntu:
  Incomplete

Bug description:
  Steps to reproduce:

  $ lxc launch ubuntu-daily:f reproducer
  $ lxc shell reproducer
  $ vgs

  Expected behaviour:

    No output (the behaviour on an EC2 instance with no VGs).

  Actual behaviour:

    Outputs "File descriptor 25 (anon_inode:[eventfd]) leaked on vgs
  invocation. Parent PID 283: -bash"
