Title:
  kernel stuck in dm_destroy

Status in linux package in Ubuntu:
  Fix Released

Bug description:
  The problem is incorrect backporting of [1] to the Ubuntu Trusty
  kernel [2].

  While original patch moves `dm_get_live_table` to the appropriate
  section mutex lock the backported code just adds another call to it
  under the mutex leaving the original call under spinlock in place.
