git question: How do I push a cherry-pick of someone else's commit?

[Rick Macklem]

I just tried to MFC a commit done to fix my commit by imp@
and it won't let be push the cherry-pick.

What's the trick to doing this?
Or do I need to get Warner to do it?
If so, it's 393b7606f9c1 in main, that needs to go into stable/13.

ps: The stable/13 build will be broken until this gets resolved.
      I'll revert the MFC if it isn't fixed soon.
