Right, I assumed MPSMIN was always 4k for the same reason you mentioned, but you can hard code it like you've done in your patch. The spec defines MPSMAX such that it's impossible to find a device with MPSMAX < 4k. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
