How would that look like?: The sysfs interface would be the same and these would be kept: /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor But it's enough to write to one instead of all and these should be links. Or does it make sense to introduce: /sys/devices/system/cpu/cpufreq/scaling_available_governors /sys/devices/system/cpu/cpufreq/scaling_governor and link above to these until deprecation time out is over. If /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor is used, one could be told to use: /sys/devices/system/cpu/cpufreq/scaling_governor instead, because the other will fall off at some time. Beside documentation is there anything else to wait for implementing this?
