What: /sys/devices/system/cpu/cpuidle/current_governor_ro Date: April, 2020 Contact: linux-pm@vger.kernel.org Description: current_governor_ro shows current using cpuidle governor, but read only. with the update that cpuidle governor can be changed at runtime in default, both current_governor and current_governor_ro co-exist under /sys/devices/system/cpu/cpuidle/ file, it's duplicate so make current_governor_ro obsolete.
