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.
