Original patch was pushed to fix the bug with os-brick in Liberty release. Liberty components use os-brick software to initiate all block storage connections. The purposed fix was backported from liberty to kilo, but only cinder drivers utilises brick in kilo, nova has its own iSCSI initiator. So the patch wouldn't fix anything, since nova compute will still work the old way.
