Subject: [PATCH 11/14] perf diff: Making compute functions static
Date: Wed, 28 Nov 2012 14:52:46 +0100 [thread overview]
Message-ID: <1354110769-2998-12-git-send-email-jolsa@redhat.com> (raw)
In-Reply-To: <1354110769-2998-1-git-send-email-jolsa@redhat.com>
All compute functions are now local to the diff command,
making them static.
