Subject: [PATCH 10/10] libperf: Add pr_err macro
Date:   Thu, 17 Oct 2019 12:59:18 +0200
Message-Id: <20191017105918.20873-11-jolsa@kernel.org>

MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

And missing include for "perf/core.h" header, which provides
LIBPERF_* debug levels and adding missing pr_err support.
