It means that when the laptop is asked to suspend to memory the kernel will prevent any tasks from being scheduled and close down most of the device drivers. Then it just waits... in other words is relies on normal kernel power management (cpufreq, cpuidle, etc) to minimise standby power. In principle by eliminating wakeups then we ensure that cpuidle can descend to it's deepest sleep state.
Is this something you added to the kernel, or was it already part of tsys'? (I've done a little mucking around in my Manjaro install, so if it was I probably wouldn't see it now lol)
