Comment 3 for bug 999256

No changes can go into stable/essex without first being merged into the development trunk, so you'd have to submit a patchset against the upstream master and then you could submit a patch against stable/essex.

If you want to hop onto IRC (Freenode.net #openstack-dev channel), I can assist you in walking through the contribution and review push process? My nick on IRC is jaypipes.

Best,
