Open Stack

I was trying to cherry pick a change in Liberty back to stable Kilo:  https://review.openstack.org/#/c/277962/
Many of the gate tests failed and I notice that appears to be the case with most of the reviews going back a while in the past.    From a quick check I did not see anything related to this change that would have caused the failure signatures I was seeing.  

Is this a known problem?   Is anyone already working on it in any capacity?
