From a96a5037ed0f52e2d86739f4a1ef985bd036e575 Mon Sep 17 00:00:00 2001 From: "Steven Rostedt (VMware)" Date: Fri, 13 Oct 2017 10:23:09 -0400 Subject: tracing, thermal: Hide cpu cooling trace events when not in use As trace events when defined create data structures and functions to process them, defining trace events when not using them is a waste of memory. The trace events thermal_power_cpu_get_power and thermal_power_cpu_limit are only used when CONFIG_CPU_THERMAL is set. Make those events only defined when that is set as well.
