From 3f1f33206c16c7b3839d71372bc2ac3f305aa802 Mon Sep 17 00:00:00 2001 From: Peter Zijlstra Date: Tue, 2 Oct 2012 15:38:52 +0200 Subject: perf: Clarify perf_cpu_context::active_pmu usage by renaming it to ::unique_pmu Stephane thought the perf_cpu_context::active_pmu name confusing and suggested using 'unique_pmu' instead. This pointer is a pointer to a 'random' pmu sharing the cpuctx instance, therefore limiting a for_each_pmu loop to those where cpuctx->unique_pmu matches the pmu we get a loop over unique cpuctx instances.
