I don't think you can put a BUILD_BUG_ON() into the structure declaration (it's code, not declarations), but I think you could just put BUILD_BUG_ON(sizeof(struct foo) - offsetof(struct foo, addr) < 8); with the user(s?) and that should catch the scenario I was worrying about? johannes -- 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
