This is happened on my system (kernel 6.1), and I verified that this PR changes fixes the original issue.

wdyt @mboelen ?

Thanks, merged!

@xnoguer should we also add a "catch" for unspecified future versions? For example, showing an exception if the kernel is at higher levels, or not needed as support for the checked options is now covered fully, including future-proof testing?

@mboelen I don't think it's needed. If the test didn't make sense from a future kernel release onward (let's say X.Y), then we would have to change the code so that PREQS_MET for test FILE-6344 is only set to "YES" when kernel version is between 3.3 and X.Y.
But there's no way to know this now (as far as I'm aware). In fact it would mean that the hidepid option stops being used or adds new possible values force us to rewrite test FILE-6344.

Yup, makes sense. Was also my thought, but wanted to double-check with you.

Thanks 👍
