Hi,

I would like to request a spec freeze exception for the new Cinder Quota
System spec [1].

Analysis of the required spec changes needed to implement the second
quota driver, as agreed in the PTG/mid-cycle, were non trivial.

In the latest spec update I just pushed there are considerable changes:

- General improvements to existing sections to increase readability.

- Description of the additional driver and reasons why we decided to
  implement it.

- Spell out through the entire spec the similarities and differences of
  both drivers.

- Change in tracking of the reservations to accommodate the new driver.

- Description on how switching from one driver to the other would work.

- Updated the driver interface to accommodate the particularities of the
  new driver.

- Updated the performance section with a very brief summary of the
  performance tests done with some code prototipe.

- Updating the phases of the effort as well as the work items.

Cheers,
Gorka.
