Subject: [PATCH 19/22] perf cpumap: Move 'has' function to libperf
Date: Tue,  7 Dec 2021 18:46:04 -0800	[thread overview]
Message-ID: <20211208024607.1784932-20-irogers@google.com> (raw)
In-Reply-To: <20211208024607.1784932-1-irogers@google.com>

Make the cpu map argument const for consistency with the rest of the
API. Modify cpu_map__idx accordingly.
