    I think this is very good viewpoint.

    The rebuilding zone fallback table and scheduler topologies need to add
    new lock.

    Oh well, who need memory and scheduler performance regression?
    Then, its /sys interface isn't so useful.


    I don't think the manual setting of node distance improve
    opteron's (or another small machine) performance.
