As for the IDQ_BUBBLE_WIDTH, you only allow 2 bits out of 3, so maximum bubble threshold is 3 instead of 7. I assume this is because you know that it cannot have more than 3 simultaneously then. Would be good to explain this a bit more in the code. > -- > [email protected] -- Speaking for myself only -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
