Thanks for checking Dan.

As your systems are much faster than mine, perhaps you could publish
the output of some script like:

$ git ls-files -- "*.[ch]" | while read file ; do \
	./scripts/checkpatch.pl -f --emacs --terse --no-summary --types=OOM_MESSAGE $file; \
  done

to someplace like kernel janitors.

That might prompt someone to submit patch series for them.

Yeah, that too.
