Subject: [PATCH 03/20] perf annotate: Get rid of annotation__scnprintf_samples_period
Date: Sat,  4 Aug 2018 15:05:04 +0200	[thread overview]
Message-ID: <20180804130521.11408-4-jolsa@kernel.org> (raw)
In-Reply-To: <20180804130521.11408-1-jolsa@kernel.org>

We have more current function tto get the title for annotation,
which is hists__scnprintf_title. They both have same output as
far as the annotation's header line goes.

They differ in counting of the nr_samples, hists__scnprintf_title
provides more accurate number based on the setup of the
symbol_conf.filter_relative variable.

Plus it also displays any uid/thread/dso/socket filters/zooms
if there are set any, which annotation__scnprintf_samples_period
does not.
