Given that this has direct revenue impact for DataCore and is time sensitive, we request the community to approve our request to add Cinder driver patch to 16.x maintenance releases ( mainly for Trains branch).
I can't speak for the Cinder maintainers and their backport policies, but from a release perspective there will be no further 16.x releases of Cinder. The stable/ussuri branch (where 16.x releases were made) passed out of maintenance phase after 16.4.2 was tagged in November of last year. The stable/train branch is where Cinder's 15.x releases were made and has been out of official maintenance since 15.6.0 last May. The stable/victoria branch (Cinder 17.x releases) is the oldest still officially maintained and is slated to be dropped from maintenance next month. -- Jeremy Stanley
