Hi, The first of the following three patches introduces notifier chaing that can be used by subsystems to prefore some hibernation-related or suspend-related operations independent of device drivers' .suspend() and .resume() callbacks. The next two patches use this mechanism for disabling/enabling the usermode helper and firmware requesting functionality before/after (respectively) the hibernation or suspend. Comments welcome.
