Hi Michal, Minchan and all, Could you please help to review it? Any suggestion is more than welcome. The aim of this patchset is to support soft offlining of movable no-lru pages, which already support migration after Minchan's commit bda807d44454 ("mm: migrate: support non-lru movable page migration"). That means this patch heavily depend on non-lru movable page migration. So when memory corrected errors occur on a non-lru movable page, we can stop to use it by migrating data onto another page and disable the original (maybe half-broken) one. -------- v4: * make isolate_movable_page always defined to avoid compile error with CONFIG_MIGRATION = n * return -EBUSY when isolate_movable_page return false which means failed to isolate movable page. v3: * delete some unneed limitation and use !__PageMovable instead of PageLRU after isolate page to avoid isolated count mismatch, as Minchan Kim's suggestion. v2: * delete function soft_offline_movable_page() and hanle non-lru movable page in __soft_offline_page() as Michal Hocko suggested.
