Before it's too late, we should consider changing the flag's name. Writing 0 to a file named pm_qos_no_power_off is a double negative, which is always awkward to think about. Instead, how about calling the file pm_qos_allow_power_off? Will the PM-QOS system allow something like that, i.e., something that is the opposite of a constraint? If not, how about naming it pm_qos_keep_power_on?
