With 64 bits there's enough address space to do that now. How does this perform compared to a traditional block based scheme? With the IBM 128b address space aren't the devices vulnerable to an errant program spraying garbage into the address space? Is it better to map each device into it's own address space? -- Jon Smirl jonsmirl@gmail.com - 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/
