Subject: [PATCH 14/22] perf cpumap: Document cpu__get_node and remove redundant function
Date: Tue, 7 Dec 2021 18:45:59 -0800 [thread overview]
Message-ID: <20211208024607.1784932-15-irogers@google.com> (raw)
In-Reply-To: <20211208024607.1784932-1-irogers@google.com>
cpu_map__get_node_id isn't used externally and merely delegates to
cpu__get_node.
