But this approach has a problem on contiguous pages. In this case, my idea can not work since friend pages are isolated, too. It means prev_page->next == next_page always is false and both pages are not LRU any more at that time. It's pointed out by Rik at LSF/MM summit. So for solving the problem, I can change the idea. I think we don't need both friend(prev, next) pages relation but just consider either prev or next page that it is still same LRU.
Any comment?
If the friend pages are isolated too, then your condition "either prev or next page that it is still same LRU" is likely to be false, no? -- All rights reversed -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxxx For more info on Linux MM, see: http://www.linux-mm.org/ .
