* core: plumbing to support numa aware scheduling * core: apply node resources compatibility upon fsm rstore Handle the case where an upgraded server dequeus an evaluation before a client triggers a new fingerprint - which would be needed to cause the compatibility fix to run. By running the compat fix on restore the server will immediately have the compatible pseudo topology to use. * lint: learn how to spell pseudo
