It should eventually depend on CONFIG_CLEANCACHE || CONFIG_FRONTSWAP though there's no sense merging this xen cleancache shim at all unless/until Linus merges cleancache (and hopefully later some evolution of frontswap). And once cleancache (and/or frontswap) is merged, there's very little reason NOT to enable one or both on a Xen guest kernel.
