Subject: [PATCH 01/11] mm: use add_page_to_lru_list()
Date: Mon,  7 Dec 2020 15:09:39 -0700
Message-ID: <20201207220949.830352-2-yuzhao@google.com> (raw)
In-Reply-To: <20201207220949.830352-1-yuzhao@google.com>

There is add_page_to_lru_list(), and move_pages_to_lru() should reuse
it, not duplicate it.
