Subject: [PATCH v3 2/5] mm/huge_memory.c: use page->deferred_list
Date: Tue, 11 May 2021 21:48:54 +0800	[thread overview]
Message-ID: <20210511134857.1581273-3-linmiaohe@huawei.com> (raw)
In-Reply-To: <20210511134857.1581273-1-linmiaohe@huawei.com>

Now that we can represent the location of ->deferred_list instead of
->mapping + ->index, make use of it to improve readability.
