Hi Linus, Without reply from Shuah, and given the importance of these fixes [1], here is a PR to fix Kselftest (broken since v6.9-rc1) for at least KVM, pidfd, and Landlock. I cannot test against all kselftests though. This has been in linux-next since the beginning of this week, and so far only one issue has been reported [2] and fixed [3]. Feel free to take this PR if you see fit.
