@hbeatty I would've merged this as a backport anyways, but generally it is the release manager's responsibility to merge backports into their release branch.

Yeah, just for future reference, the Release Manager "owns" the release branch, in this case 4.1.x. It's ok for someone to say "can I merge this" and them to say yes. But we're generally not supposed to merge anything into a release branch without the approval of the RM
