How will a ionice on steriods that will defer servicing IO when the IO system QoS limit doesn't meet the updatedb process's level is too low, not solve this? In that case the updatedb process will simply block on IO, will hence not be runnable and thus not drain your battery. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
