There is commented-out code like this in various places in this patch.

I am pretty sure that scripts/checkpatch.pl should flag that.
See https://docs.kernel.org/dev-tools/checkpatch.html
and https://docs.kernel.org/process/submitting-patches.html#style-check-your-changes

I personally just keep a checklist of things to remember before sending a patch.
(rebase as needed, clang-format -i (for Landlock files), run tests, check commit
metadata, git format-patch with -v and --cover-letter, scripts/checkpatch.pl,
edit cover letter, git send-email)
