Bug description:
  [Impact]

   * Cannot hibernate & resume from a swapfile

  [Test Case]

   * Create or enlarge swapfile to be big enough for hibernation
   * Attempt to hibernate and resume

  [Regression Potential]

   * Hibernation is not reliable technology in itself, and multiple
  things may cause failure to resume. Thus it is sufficient to validate
  this bug after swapfile is attempted for hibernation and the disk
  offset kernel parameter is modified. Irrespective if actual suspending
  or resume were successful or not.

  [Other Info]
   
   * Original bug report

  In 4.17 a new attribute is introduced to configure the hibernation
  resume offset. Since Ubuntu enables a swapfile by default this
  attribute is important to be able to make hibernation work "out of the
  box".

  The patch in the kernel is here:
  https://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git/commit/?h=linux-next&id=355064675f1c997cea017ea64c8f2c216e5425d9
