Subject: [PATCH 14/15] perf hists browser: Use hierarchy hpp list
Date: Mon,  7 Mar 2016 16:44:50 -0300	[thread overview]
Message-ID: <1457379891-28516-15-git-send-email-acme@kernel.org> (raw)
In-Reply-To: <1457379891-28516-1-git-send-email-acme@kernel.org>

From: Namhyung Kim <namhyung@kernel.org>

Now hpp formats are linked using perf_hpp_list_node when hierarchy is
enabled.  Like in stdio, use this info to print entries with multiple
sort keys in a single hierarchy properly.
