A reference is fine - it's just that people actively use Fixes to mean
"the specific commit introduced a bug and anything with the referenced
commit might want this fix" which is different to "The change in this
commit caused me to notice this other thing" which is more what you've
got here.  For this case some words in the commit log saying something
like "The foo change in commit X ($subject) exposed $existing_problem"
is probably what you're looking for.

I've queued it for v5.16, I'm likely to move it to v5.15 - it's just
warnings on a very small subset of systems but OTOH it's pretty safe.
