Subject: [PATCH v12 06/16] mm/thp: clean up lru_add_page_tail
Date: Thu, 11 Jun 2020 14:16:39 +0800 [thread overview]
Message-ID: <1591856209-166869-7-git-send-email-alex.shi@linux.alibaba.com> (raw)
In-Reply-To: <1591856209-166869-1-git-send-email-alex.shi@linux.alibaba.com>
Since the first parameter is only used by head page, it's better to make
it stright.
