Most of flags in this patch is for LRU and modfied > under mz->lru_lock but we'll add another flags which is not for LRU soon. > (lock_page_cgroup() will use LOCK bit on page_cgroup->flags) > So we use atomic version here. > Seems quite straightforward Acked-by: Balbir Singh <balbir@...ux.vnet.ibm.com> -- Balbir -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
