[RFC PATCH 0/2] PM: hibernate: opportunistic memory reclaim

Here is the first attempt to provide an interface that allows user-space tasks to trigger an opportunistic memory reclaim before hibernating a system. Reclaiming memory in advance (e.g., when the system is idle) allows to reduce the size of the hibernation image and significantly speed up the time
