Subject: [PATCH 4/8] perf tools: Introduce struct hist_browser title callback
Date: Mon, 20 Jun 2016 23:58:15 +0200	[thread overview]
Message-ID: <1466459899-1166-5-git-send-email-jolsa@kernel.org> (raw)
In-Reply-To: <1466459899-1166-1-git-send-email-jolsa@kernel.org>

We can now setup title callback for hist_browser,
which will be useful in following changes to
create customized hist_browsers.

This also separates struct perf_evsel dependency
out of hist_browser basic code.
