New Revision: 323961
URL: https://svnweb.freebsd.org/changeset/base/323961

Log:
  Since the page "frame" doesn't belong to a vm object, it can't be paged
  out.  Since it can't be paged out, it is never actually enqueued in a
  paging queue.  Nonetheless, passing PQ_INACTIVE to vm_page_unwire()
  creates the appearance that the page "frame" is being enqueued in the
  inactive queue.  As of r288122, we can avoid this false impression by
  passing PQ_NONE.
