@chuanga Can you please clean the history (there should be one commit only) ?

[cmonr]

Waiting for the commit history to be swashed into a single commit, since the change-set is small.

@cmonr I even think a simple git cherry-pick 1051e33 on top of master should work fine.
@chuanga you'd have to force push to the branch.
You can also fetch it from the branch on my fork.

I tried to rebase and recommit changes. I hope this is now ok

Interesting. Looks like this was hit with a bug this PR is aiming to fix: #7070

Will rerun in the case that it happens to not show up again.
