KOSAKI Motohiro 08fc468f4e vmscan: isolate_lru_pages(): stop neighbour search if neighbour cannot be isolated ... isolate_lru_pages() does not just isolate LRU tail pages, but also isolates neighbour pages of the eviction page. The neighbour search does not stop even if neighbours cannot be isolated which is excessive as the lumpy reclaim will no longer result in a successful higher order allocation. This patch stops the PFN neighbour pages if an isolation fails and moves on to the next block.
