Cinder code clean-up patches
As discussed in the Cinder weekly meeting on July 2nd, 2014, patches that are pure code clean-up (PEP8/HACKING related, test assertion and other style fixes, log message translation patches, python3 fixes, etc) will now be batched and merged in the week after each milestone, rather than randomly during the milestone.
To mark these, a core dev will -2 the patch with the string 'code_cleanup_batching' somewhere in the comment. A link to this article is also probably nice.
The search https://review.openstack.org/#/q/project:openstack/cinder+comment:code_cleanup_batching+-status:merged,n,z should find all reviews for the next merge window.
