I don't use or follow Linux but I do stumble upon news about it here and there, and I saw a video just a month or so ago, about Linus going off on RISC-V etc.
That one is comparatively nicer than some of the older stuff telling people to stop deepthroating Microsoft or to kill themselves or to shut the fuck up.
That said I really didn’t that that contributor creating a helper function like that to do some bitwise stuff was such a big deal, I think Linus overreacted and I don’t even know that I agree with his take that on it, but I do think it is probably bad to have a big change like this late in the release window.
Maybe it was this, not sure, not gonna go dig it up: https://www.youtube.com/watch?v=8E8Gb7Ikm2o
