Any suggestions? > I will probably send v1 for review without the offsets. I think it's ok just to replace the offset number with a name. If you are concerned about readability, we could probably wrap the "for loops" in the math calculations with a more serious sounding macro eg. "#define foreach_smm_offset(val, start_offset, jump, count)" :) > Paolo -- 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/
