Increasing its size by four bytes will cause memory scribbles in userspace applications. That's fixable by suitably adjusting sysinfo._f, but given the lack of version information in the sysinfo struct, I'm not sure how useful this change really is. -- To unsubscribe from this list: send the line "unsubscribe linux-ia64" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
