Who can review this? |
"Update with rebase" appears to not be enabled on the repo, so I did it with a merge commit. Hopefully that's fine since it gets squashed anyway. FWIW, I consider this a pretty low-risk patch; I would expect identical machine code. |
Unfortunately it doesn't get squashed when we merge to the repo. We use a custom script to merge to the release branch. You need to manually squash / rebase and push to the branch, but I'll handle it. |
