You surprise me, Christoph, I'd expected you to approve of CaT's.
If tmpfs already defaulted to 50% of ram+swap, then I'd agree with you. But it has all along been in terms of RAM, so I think it's better to continue in that way. (We could add options to allow +swap in too, but I'm not terribly interested.)
If people really wanted their tmpfs pages to go out to disk, I think they'd be choosing a more sophisticated filesystem to manage that: swap is a vital overflow area for tmpfs, not its home.
