From: Steven Rostedt (VMware) Date: Fri, 13 Oct 2017 14:21:50 +0000 (-0400) Subject: tracing, thermal: Hide devfreq trace events when not in use X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b5ca66f9c0cf8c1cfeca12f001b86486c670279d;p=linux.git tracing, thermal: Hide devfreq 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_devfreq_get_power and thermal_power_devfreq_limit are only used when CONFIG_DEVFREQ_THERMAL is set. Make those events only defined when that is set as well.
