  Log:
  SVN rev 208773 on 2010-06-03 10:20:08Z by kib
  
  Sometimes vnodes share the lock despite being different vnodes on
  different mount points, e.g. the nullfs vnode and the covered vnode
  from the lower filesystem. In this case, existing assertion in
  vop_rename_pre() may be triggered.
  
  Check for vnode locks equiality instead of the vnodes itself to
  not trip over the situation.
