So Linus fucked it up?!

No. According to the author, Linus Torvalds was the only person who've noticed the problem in the final merge and applied a fix manually before merging it to the mainline. However, the stable kernel trees picked up the old patch, and the broken version was merged to all stable trees silently. The author blames Greg K.H. for fxxking it up.

The fix was done as part of the merge commit itself, it should have been a separate patch.

So one could argue that Linus kinda failed in fixing the problem he has identified correctly.

Makes sense, thanks for the clarification.

did you read the article or only one phrase of it, the one about Linus? He did a correct fix but was ignored by the other developer.

I did read it till the end, but I got confused by the sentence "To clarify why this fix is bad, ..." in the paragraph after Linus's fix, so from there on I thought the article is talking about his fix of the fix. My bad.
