What's not particularly nice though is to hide these in a macro, which itself may be part of a larger macro or code fragment also using small numbers. We probably ought to be a bit more inteligent about how we choose these numbers inside macros, rather than just randomly picking some and hoping that they don't clash. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net. -- 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/
