Subject: [GIT PULL] Kselftest fixes for v6.9

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.

Regards,
 Mickaël
