For relands, you can just use `Differential Revision: https://reviews.llvm.org/D138321` instead of `Related differential revision: https://reviews.llvm.org/D138329`.
`Revert "Revert ` can be replaced with `Reland` to emphasize that it is a reland (it can be omitted as well). A reland should include the original commit message. You may additionally mention what issue it fixes.
