You shouldn't make the core scheduler dependent upon some hwmon module. I'd sugggest adding some register_cpu_temperature_monitor() function in the scheduler then permit suitable monitoring modules to register themselves in their module_init() functions. Use a notifier chain from notifier.h. The CPU scheduler will walk that chain calling into the registered drivers at a suitable time. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
