IMHO, what everybody agrees on, is that swap-prefetch has a positive effect in some cases, and nobody can prove an adverse effect (excluding power consumption). The reason for this positive effect is also crystal clear: It prefetches from swap on idle into free memory, ie: it doesn't force anybody out, and they are the first to be dropped without further swap-out, which sounds really smart. Conclusion: Either prove swap-prefetch is broken, or get this merged quick.
