Subject: [BUG Fix Patch 5/6] Bug fix: Fix the wrong comments of map_entries.
Date: Tue, 15 Jan 2013 10:54:26 +0000 [thread overview]
Message-ID: <1358247267-18089-6-git-send-email-tangchen@cn.fujitsu.com> (raw)
In-Reply-To: <1358247267-18089-1-git-send-email-tangchen@cn.fujitsu.com>
Now we have a map_entries_lock to protect map_entries list.
So we need to update the comments.
