Well, this is kind of expected, since Cinder scheduler started as a
copy-paste of the Nova scheduler :-) But they already started diverging

Jay,
Hi Jay, yes we were working about putting all common stuff in
oslo-scheduler. (not only filters)
As a result of this work we understood, that this is wrong approach.
Because it makes result code very complex and unclear. And actually we
didn't find the way to put all common stuff inside oslo
I noticed that there is already a bp in oslo tracing what I want to do:

Jay,
One quick comment. "cinder/openstack/common/scheduler" should have
only files that are in "oslo-incubator/openstack/common/scheduler".
So in #2, Can you please clarify what you mean? ("Move all
filters/weight logic in cinder from cinder/scheduler to
cinder/openstack/common/scheduler")
thank
Greetings,
Now in oslo, we already put some scheduler filters/weights logic there and
cinder is using oslo scheduler filters/weights logic, seems we want both
nova&cinder use this logic in future.
Found some problems as following:
1) In cinder, some filters/weight logic reside in
cinder/openstack
