From 1eaf496ed386934f1c2439a120fe84a05194f91a Mon Sep 17 00:00:00 2001 From: Ian Rogers Date: Sat, 27 May 2023 00:22:03 -0700 Subject: [PATCH] perf pmu: Separate pmu and pmus Separate and hide the pmus list in pmus.[ch]. Move pmus functionality out of pmu.[ch] into pmus.[ch] renaming pmus functions which were prefixed perf_pmu__ to perf_pmus__.
