Cool, I didn't know this.  I usually format it like

ed9e923c3c ("x86: move SMM property to X86MachineState", 2019-12-17)

I can see why most developers don't use "git describe", because at least
those that also are maintainers will often have intermediate tags after
a release.

Anyway I've queued this patch, thanks.
