I was wondering if you provide a little bit more background on the QoS item, "-- remove RPC upgrade tech debt that we left in L (that should open path for new QoS rules that are currently blocked by it);”.  Is this related to the issue you point out in the commit message for the https://review.openstack.org/#/c/211520 change?  Does this block work on implementing QoS DSCP in Mitaka, and if so are there bugs that we can pitch in to in order to get past it?

I talked to some nova folks involved in upgrades there, and we may join the armies on that since general upgrade strategy should be similar throughout the meta-project.
