No, this is a bug step back. I think we really want to treat this as PREFERRED. It doesn't have much to do with the BIND semantic at all. At this stage there should be 2 things remaining - syscalls plumbing and 2 pass allocation request (optimistic preferred nodes restricted and fallback to all nodes). -- Michal Hocko SUSE Labs
