Our current way of doing it is going by patch-id, and it's not great
either, because there is more than one way to create a patch from a git
commit. We've discovered this when Linus recommended that people send
patches with the --histogram algorithm, which broke a bunch of our
stuff. :)

E.g. here's a recent commit that has a Fixes:

git show c0297e7dd50795d559f3534887a6de1756b35d0f | git patch-id --stable | cut -d' ' -f1
c2f5c42a5a3bc05ffacd9679dd367e4a2207b018

it successfully maps to the patch:
https://lore.kernel.org/all/?q=patchid%3Ac2f5c42a5a3bc05ffacd9679dd367e4a2207b018

I only put this here for academic purposes -- I really don't want you to
go that route, because it's fragile (more fragile than git notes, and
that's saying something).
