Yep, you found the right patch. That is a known issue right now and we should
hopefully have the fix merged very shortly.

In the meantime, you could add this to your local.conf:

CINDER_BRANCH=refs/changes/46/626146/3

With that, devstack will pull down that version of the code and you should be
able to get by this failure until we merge the fix. As of this moment, there is
just a pep8 error that is preventing that from merging. That will not impact
the ability to actually run the code.

Once that merges you can take that line out of the local.conf file to just get
the current code from master.

Hope that helps.
