From: Xing Yang Date: Sat, 21 Nov 2015 14:17:51 +0000 (-0500) Subject: ScaleIO QoS Support X-Git-Url: https://review.fuel-infra.org/gitweb?a=commitdiff_plain;h=56cae96a06a7b74a5de41b596668cea257729d93;p=openstack-build%2Fcinder-build.git ScaleIO QoS Support This patch adds QoS support to the ScaleIO driver by using Cinder QoS specs. Also refactored logging and fixed formatting errors.
