xen/xenpaging.pageout_policy.patch

Subject: xenpaging: call pageout policy function in xenpaging_evict_page 

Notify policy about a page that was just paged out to disk.
Up to now the code called the opposite function, which clears the
(xenpaging internal) reference bit, instead of setting it and marking
the page as gone.
