Subject: [PATCH 07/21] perf callchain: Add callchain_cursor_snapshot()
Date: Thu, 23 Jan 2014 09:13:51 +0900 [thread overview]
Message-ID: <1390436045-16830-8-git-send-email-namhyung@kernel.org> (raw)
In-Reply-To: <1390436045-16830-1-git-send-email-namhyung@kernel.org>
The callchain_cursor_snapshot() is for saving current status of the
callchain. It'll be used to accumulate callchain information for each node.
