You will also need to sign off your commits with git commit -s (or `git commit -s --amend to amend an existing commit)
There was apparently some confusion regarding the git sign-off and this PR is continued over at https://github.com/servo/servo/pull/40473.
For the record / next time, you can use git rebase --interactive and git commit --amend to edit your commits (including adding a sign-off) - next time you can just update the original PR.
