Why do you lack confidence in RHEL? haha :)

I have confimed that both RHEL 9 and 10 have backported this
feature (commit 2d5de004e009).

As RHEL 9 is based on an older kernel(5.14) but includes this
backport, changing this to .min_kver = "6.1" will cause the
test to be incorrectly skipped (TCONF) on RHEL 9 systems.

Anyway, back to the topic, what is the point of creating this patch?
Anything I missed?
