We recently added the change in global background reclaim which counts the return value of soft_limit reclaim. Now this patch adds the similar logic on global direct reclaim. We should skip scanning global LRU on shrink_zone if soft_limit reclaim does enough work. This is the first step where we start with counting the nr_scanned and nr_reclaimed from soft_limit reclaim into global scan_control. The patch is based on mmotm-2011-04-14-15-08 plus 0001-check-pageunevictable-in-lru_deactivate_fn.patch from Minchan. Ying Han (2): Add the soft_limit reclaim in global direct reclaim.
