Just picking up on that bracketed part: Can we flag the userland interface (and uswsusp) as being planned for eventual removal now... or at least agree to work toward that? I'm asking because if we're going to make a go of getting the in-kernel code in much better shape, and we have Rafael, Jiri and I - and you? - all pulling in the same direction to improve it, there's going to come a point (hopefully not too far away) where uswsusp is just making life too difficult, and getting rid of it will be a big help.
