Subject: [PATCH 08/27] perf callchain: Add callchain_cursor_snapshot()
Date: Sun, 1 Jun 2014 15:31:19 +0200 [thread overview]
Message-ID: <1401629498-8726-9-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1401629498-8726-1-git-send-email-jolsa@kernel.org>
From: Namhyung Kim <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.
