Subject: [PATCH 13/14] lru/vmscan: using per lruvec lru_lock in get_scan_count
Date: Tue, 20 Aug 2019 17:48:36 +0800 [thread overview]
Message-ID: <1566294517-86418-14-git-send-email-alex.shi@linux.alibaba.com> (raw)
In-Reply-To: <1566294517-86418-1-git-send-email-alex.shi@linux.alibaba.com>
The lruvec is passed as parameter, so no lruvec->pgdat syncing needed.
