My opinion we have to establish strict rules what we print in case of prefixed pointer (when #ifdef is false in some cases, e.g. struct clk) or fixed type values, such as phys_addr_t. I mean to always have a maximum width for the type on the running architecture. -- With Best Regards, Andy Shevchenko -- 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/
