The problem of how to start and stop (some) userspace is not specifically system power management-related, nor top-down, /sys/power/state-suspend related. PM is just one potential user. It's hard to see how the Android opportunistic suspend approach would be useful for the other use-cases (e.g., checkpoint/restart). On the other hand, it's easier to see how something like freezer cgroups could be useful for system power management and checkpoint/restart. And the Android opportunistic suspend patches have design problems - they definitely do not come for free, as noted in [1][2][3] (among others' comments). - Paul 1.
