Serious review of python code is beyond my background, but I did a test
on this against opensuse/leap:15.6's python3-Sphinx_4_2_0, which comes with
python 3.6.15.

Running "./scripts/kernel-doc.py -none include/linux/rcupdate.h" emits this:

------------------------------------------------------------------------
Traceback (most recent call last):

This error appeared in 12/12.  No errors with python3 >=3.9.

I'm not sure but asking compatibility with python <3.9 increases
maintainers/testers' burden.  Obsoleting <3.9 all together would
make everyone's life easier, wouldn't it?

    Thanks, Akira
