I even run the (admittedly premature but promising) benchmarks on my patch on a 4k blocksized filesystem... Guess what, you can even still mount a 1k fs on a 2.6 kernel. The main advantage I can see in your patch is that distributions won't need to ship a 64k PAGE_SIZE kernel rpm (but your single rpm will be slower). - 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/
