    nfs - Fix utimes() bugs in NFS
    
    * Over the years I have tried very hard to avoid flushing pending writes
      when issuing [l]utimes() operations (i.e. setattr VOPs) in NFS, but
      it just causes issues every time.
    
    * Give up.  We now flush pending writes prior to setattr() operations which
      adjust mtime.  This will slow down certain operations such as cp -Rp,
      cpdup, etc, but should improve the consistency and reliability of
      timestamps.
