I will not be sponsoring this for FFE. I think its a little late to land something to such a core piece of code. And I am more interested in spending my bandwidth fixing bugs and getting things ready for RC1. > > Thanks, > Yathi. > > > _______________________________________________ > OpenStack-dev mailing list > [email protected] > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > _______________________________________________ OpenStack-dev mailing list [email protected] http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
