It's a bug alright - in the kernel. How long have you been a

maintainer? And you *still* haven't learnt the first rule of kernel


If a change results in user programs breaking, it's a bug in the

kernel. We never EVER blame the user programs. How hard can this be to


To make matters worse, commit f0ed2ce840b3 is clearly total and utter

CRAP even if it didn't break applications. ENOENT is not a valid error

return from an ioctl. Never has been, never will be. ENOENT means "No

such file and directory", and is for path operations. ioctl's are done

on files that have already been opened, there's no way in hell that

ENOENT would ever be valid.

Shut up, Mauro. And I don't _ever_ want to hear that kind of obvious

garbage and idiocy from a kernel maintainer again. Seriously.

I'd wait for Rafael's patch to go through you, but I have another

error report in my mailbox of all KDE media applications being broken

by v3.8-rc1, and I bet it's the same kernel bug. And you've shown

yourself to not be competent in this issue, so I'll apply it directly

and immediately myself.


Seriously. How hard is this rule to understand? We particularly don't

break user space with TOTAL CRAP. I'm angry, because your whole email

was so _horribly_ wrong, and the patch that broke things was so

obviously crap. The whole patch is incredibly broken shit. It adds an

insane error code (ENOENT), and then because it's so insane, it adds a

few places to fix it up ("ret == -ENOENT ? -EINVAL : ret").

The fact that you then try to make *excuses* for breaking user space,

and blaming some external program that *used* to work, is just

shameful. It's not how we work.

Fix your f*cking "compliance tool", because it is obviously broken.

And fix your approach to kernel programming.

  1. I may be an average corporate backend dev, but if anyone I work with would react in this way after any kind of mistake I did, I would report the situation / leave immediately.

    Honest feedback is surely key to keep quality, innovation, and skills high – the thread has indeed a few lines of honest feedback (don't break user-space, wrong error) and the rest are just insults. I am pretty sure it goes against the Code of Conduct [1]


    EDIT: Just saw 2012, I guess CoC was not in place back then
