Subject: [PATCH v16 06/22] mm/thp: clean up lru_add_page_tail
Date: Sat, 11 Jul 2020 08:58:40 +0800 [thread overview]
Message-ID: <1594429136-20002-7-git-send-email-alex.shi@linux.alibaba.com> (raw)
In-Reply-To: <1594429136-20002-1-git-send-email-alex.shi@linux.alibaba.com>
Since the first parameter is only used by head page, it's better to make
it explicit.
