So returning "long" from here doesn't make any sense. You really have to limit the usable lengths to the range of an 'int' all the way up to the code in net/socket.c -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
