Subject: [PATCH 13/22] perf cpumap: Rename empty functions.
Date: Tue,  7 Dec 2021 18:45:58 -0800	[thread overview]
Message-ID: <20211208024607.1784932-14-irogers@google.com> (raw)
In-Reply-To: <20211208024607.1784932-1-irogers@google.com>

Remove cpu_map from name as a cpu_map isn't used. Pass a const pointer
rather than by value to avoid unnecessary copying.
