    [patch] remove gendisk->stamp_idle field · 20e5c81f
    Chen, Kenneth W authored
    struct gendisk has these two fields: stamp, stamp_idle.  Update to
    stamp_idle is always in sync with stamp and they are always the same.
    Therefore, it does not add any value in having two fields tracking
    same timestamp.  Suggest to remove it.
    
    Also, we should only update gendisk stats with non-zero value.
    Advantage is that we don't have to needlessly calculate memory address,
    and then add zero to the content.
