Also, even though pgcl scales "perfectly" wrt. highmem (nm the code being a train wreck), the raw capacity increase is needed. There are enough other reasons to go through with ABI-preserving page clustering that they're not really in competition with each other. Looks good to me. I'll spin it up tonight. -- wli - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
