Subject: [RFC v1 06/19] mm, vmscan: use for_each_node in do_try_to_free_pages()
Date: Thu, 21 Nov 2019 23:17:58 +0800 [thread overview]
Message-ID: <20191121151811.49742-7-fly@kernel.page> (raw)
In-Reply-To: <20191121151811.49742-1-fly@kernel.page>
In do_try_to_free_pages(), we want to traverse node instead of zone,
so use for_each_node instead of for_each_zone.
