If anyone has any objections, please let me know. ------------------ From: Pengjie Zhang [ Upstream commit 85524e651d20944399322d46fb97960337831d43 ] The ondemand governor implementation accepts sampling_down_factor values from 1 to 100000 via MAX_SAMPLING_DOWN_FACTOR, but the documentation in admin-guide/pm/cpufreq.rst still says the valid range is 1 to 100. Update the documentation to match the actual code.
