Since the offsets are unsigned and 32-bit this will do the wrong thing when used as an offset of a 64-bit pointer as the 32-bit "negative" value will be zero instead of sign-extended. If this theory proves true, the fix is to make the offsets signed 32-bit quantities. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
