Mark Johnston be801aaaef Fix a race in release_page(). ... Since r354156 we may call release_page() without the page's object lock held, specifically following the page copy during a CoW fault. release_page() must therefore unbusy the page only after scheduling the requeue, to avoid racing with a free of the page. Previously, the object lock prevented this race from occurring. Add some assertions that were helpful in tracking this down.
