Strongly disagree for two reasons 1. We don't want to leave the other ioctls broken and non-compliant if we can avoid it. 2. The userspace code here has quite reasonable expectations which are that TIOCGPTN is not an unknown ioctl but is invalid to use in this situation. So we should just fix TIOCGPTN on a pty with no suitable name answer to return -EINVAL (even though it would be fun to break userspace and make Linus teach more rude words to non English speakers). In this case I think the userspace expectations are actually perfectly fair anyway even without considering the rather important criterion of 'it worked last week') Alan -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
