The general pattern is to move the ioctl compat handlers into the drivers themselves, so putting in a compat handler in the IDE layer is the way to go. -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
