The point which your parent post made, and which I was implying in my original post, is that if the committer was willing to commit such a clumsy "fix", what else might they commit in other places?
Nobody said the committer was not intelligent nor prolific. What was implicitly brought into question was the judgement of the person.
"But all the people who reviewed and accepte the commit!..." Sometimes reviewers don't pay full attention (because they are busy). Or sometimes they don't feel confident to challenge someone. Or they may be inexperienced.
I understood, and I do believe you're experiencing the Dunning-Kruger effect as well. First, the graphics subsystem of Linux is in fact one of those that puts more weight on reviews even for code authored by the maintainers.
Second, do you have any idea if the issue being solved here and what a less clumsy fix would look like. Nobody is denying that it's clumsy, which is why it is being reverted, but have you evaluated the alternatives or even bothered to look up mailing list discussions before making your conclusions about it?
