(For the record, I do not think this is going to be hibernation-replacement any time soon. But it is functionality useful for other stuff -- dump memory and continue -- and yes it may be able to do hibernation in the long term. It really comes from the other side of reliability: * swsusp is "if your kernel is perfectly healthy, it will work" while this, coming from kdump is * "if your kernel is not completely trashed, it should work" ...which is why can't use swsusp to do dump memory and continue -- you want to do dumps on "slightly broken" systems. And yes, as a sideeffect it may be able to do hibernation... why not, lets see how it works out).
