    kernel - Rearrange struct vnode fields
    
    * Rearrange vnode fields for improved SMP performance.  Place v_auxrefs
      and v_refcnt together but in a different cache line than v_lock.  This
      allows concurrent SMP operations to effectively pipeline atomic ops
      on these fields that we haven't yet been able to get rid of, improving
      performance.
