Agreed. Sorry if I gave the impression that I was trying to rush this
into 3.19. I just wanted to make sure that Steve was aware of the
dependency.

Without knowing how that consistency code will look, how can we "make
sure" that this code can be easily extended to support it? I don't
think we should hold up this first step based on what we think the
consistency code might look like. The code is not that complex right
now. That was the point :) We can always adapt things.

I was hoping this first step would go into next via Steve's tree and go
upstream for 3.20 (hopefully) from there. I would be against anything
that tries to expand the feature set before this base functionality gets
upstream. However, if we want to have a tree to gather fixes before
3.20, which I think is what you are suggesting, that works for me. We
would need to agree explicitly that, in this tree, patches would need
both a RH and SUSE ack to be accepted.

Thanks,
Seth
