It will be pushed if I get no objections before 11/29/18. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. If the code is different (ie: not only metadata diffs), due for example to a change in context or macro names, please double check it. Thanks.
