KAMEZAWA Hiroyuki 0c0e619589 memory unplug: page offline ... Logic. - set all pages in [start,end) as isolated migration-type. by this, all free pages in the range will be not-for-use. - Migrate all LRU pages in the range. - Test all pages in the range's refcnt is zero or not. Todo: - allocate migration destination page from better area. - confirm page_count(page)== 0 && PageReserved(page) page is safe to be freed.. (I don't like this kind of page but.. - Find out pages which cannot be migrated. - more running tests. - Use reclaim for unplugging other memory type area.
