That said, every PR receives a bot comment indicating that the GH repo is a mirror and the user needs to submit a patch to LKML. And yet there are currently 312 open PRs on the repo. I've always wondered how people manage to know enough about the kernel to be able to contribute a PR to it, yet don't know the GH repo is a mirror and seemingly ignore the bot response and leave their PR opened.
I'm surprised with the massive number of auto-close-bots on GH (combined with the kernel's development culture) that they don't just auto-close them
I've also never understood why GH allows turning off issues, but not turning off PRs
People are aware the PR isn't going to be accepted; they just want to publish it somewhere.
It's an easy mistake to make, the code is there and there's nothing to suggest it's a mirror.
