Clark, would you be so kind, at your conveniencew, as to remove the 
manila driverfixes/ocata branch?

There are no open changes on the branch and `git log 
origin/driverfixes/ocata ^origin/stable/ocata --no-merges --oneline` 
reveals no commits that we need to preserve.

Thanks much!

Git garbage collection will delete and cleanup commits if they are not discoverable when working backward from some ref. This is why our old stable branch deletion process required we tag the stable branch as $release-eol first. Looking at `git log origin/driverfixes/ocata ^origin/stable/ocata --no-merges --oneline` there are quite a few commits on the driverfixes branch that are not on the stable branch, but that appears to be due to cherry pick writing new commits. You have indicated above that you believe the two branches are in sync at this point. A quick sampling of commits seems to confirm this as well.
