I nuked the whole block:
/*
* Page is from a zone we don't care about.
* Don't drop page cache entries in vain.
*/
if (page->zone->free_pages > page->zone->pages_high) {
/* the page from the wrong zone doesn't count */
count++;
goto unlock_continue;
}
Commenting it out made ac19 perform almost as good as ac4 (it looked a bit
faster).
I don't know how it would affect boxes with more than one zone, but my gut
feeling is that it won't hurt and might make them even a bit faster.
