Currently it's not possible to enable hibernation without also enabling generic swap for a given swap area. These two use cases are not the same. For example there may be users who want to enable hibernation, but whose drives don't have the write endurance for generic swap activities. Add a new SWAP_FLAG_NOSWAP that adds a swap region but refuses to allow generic swapping to it. This region can still be wired up for use in suspend-to-disk activities, but will never have regular pages swapped to it.
Just to confirm: things like /proc/meminfo won't show this "swap that's not actually swap" as free/total swap, correct? Maybe it's worth spelling the expected system behavior out here.
