Subject: [PATCH] perf cpumap: Migrate to libperf cpumap api
Date:   Thu, 17 Feb 2022 09:27:26 +0800
Message-Id: <20220217012726.27858-1-tangmeng@uniontech.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Feedback-ID: bizesmtp:uniontech.com:qybgforeign:qybgforeign1
Precedence: bulk

Switch from directly accessing the perf_cpu_map__cpu to using the
appropriate libperf API when possible. Using the API simplifies
the job of refactoring use of perf_cpu_map__cpu.
