Subject: [PATCH 2/3] lglock: make the per_cpu locks static
Date: Tue, 9 Oct 2012 11:46:39 +0800 [thread overview]
Message-ID: <1349754403-4798-2-git-send-email-laijs@cn.fujitsu.com> (raw)
In-Reply-To: <1349754403-4798-1-git-send-email-laijs@cn.fujitsu.com>
The per_cpu locks are not used outside nor exported.
Add a "static" linkage keyword to it.
