Subject: [PATCH 12/22] perf cpumap: Simplify equal function name.
Date: Tue, 7 Dec 2021 18:45:57 -0800 [thread overview]
Message-ID: <20211208024607.1784932-13-irogers@google.com> (raw)
In-Reply-To: <20211208024607.1784932-1-irogers@google.com>
Rename cpu_map__compare_aggr_cpu_id to aggr_cpu_id__equal, the cpu_map
part of the name is misleading. Equal better describes the function than
compare.
Switch to const pointer rather than value as struct given the number of
variables in aggr_cpu_id.
