Subject: [PATCH 4/7] libperf: Move nr_groups to evlist::nr_groups
Date: Tue,  6 Jul 2021 17:17:01 +0200	[thread overview]
Message-ID: <20210706151704.73662-5-jolsa@kernel.org> (raw)
In-Reply-To: <20210706151704.73662-1-jolsa@kernel.org>

Moving evsel::nr_groups to perf_evsel::nr_groups, so we can move
the group interface to libperf.

Signed-off-by: Jiri Olsa <jolsa@kernel.org>
