Open Stack

Hi Swift folks,

Today the following patch was abandoned and I contacted with the author, 
so I would like to take it over if nobody else is chafing to take it.
Is it OK?

https://review.openstack.org/#/c/80421/

If it is OK, I will proceed it with following procedure.
(1) Open new bug report (there is no bug report for this)
    I'm not sure that I should write a BP instead of a bug report.
(2) Make a patch based on the current patch on gerrit

Cheers,
Hisashi Osanai
