Subject: [PATCH 30/73] libperf: Add perf_evlist__id_add function
Date:   Fri, 13 Sep 2019 15:23:12 +0200
Message-Id: <20190913132355.21634-31-jolsa@kernel.org>

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Adding perf_evlist__id_add function to libperf
as internal function. We already have the heads
member in 'struct perf_evlist'.
