Sorry, I was barking up the wrong tree.

An example of messages from opensuse/leap:15.6's Sphinx looks like this:

WARNING: kernel-doc './scripts/kernel-doc.py -rst -enable-lineno -export ./fs/pstore/blk.c' processing failed with: AttributeError("'str' object has no attribute 'removesuffix'",)

The "removesuffix" is already there in scripts/lib/kdoc/kdoc_parser.py at
current docs-next.  It was added by commit 27ad33b6b349 ("kernel-doc: Fix
symbol matching for dropped suffixes") submitted by Matthew.

But I have to ask, do we really want the compatibility with python <3.9
restored?

        Thanks, Akira
