Adding a layer of indirection makes code changes easier, but makes the code slower. Arguments are passed in registers, and putting an additional level of indirection only matters if you can't change all the CC modules. Since this is the kernel and API compatability doesn't matter, just pass more arguments. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
