Why do you think so? I thought they can always be used in parallel. Consider 2 or more policies, one can have ondemand as the governor, whereas other one can have conservative. If CPUs go online/offline or if governors are switching in parallel, then cpufreq_governor_dbs() can very much run in parallel for ondemand and conservative. Or am I missing something here ? -- viresh
