The performance become a critical factor for the execution of the jitted filter. But yes, avoiding passing the argument and doing the pointer operation later on could save some instructions which is both good for compilation performance and also makes the function simpler as you said. -- markos -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
