From 3ac23d199c2bc3bc2a2b31c803e7c5d841959670 Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Tue, 4 Jan 2022 22:13:16 -0800 Subject: perf cpumap: Simplify equal function name 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().
