I'm also thinking that under Linux since we never use userspace to alloc memory for the balloon, we don't need to involve userspace at all, the drivers interrupt handler could detect the event that the host wants to change the balloonsize itself and start a workqueue item which then asks for what the new size should be and do the adjustment all inside the kernel. I think that will even lead to simpler code as we no longer need to track the balloon userspace owner and do reclaim when it dies. Typing this out I really see no reason to not do this inside the kernel, so I think I'm going to implement that right away / for the [RFC v2] I plan to post later today or tomorrow.
