  Modified files:
    sys/miscfs/union     union_subr.c union_vnops.c 
  Log:
      Make sure file after VOP_OPEN is VMIO'd when transfering control from
      a lower layer to an upper layer.  I'm not sure how necessary this is
      for reading.
  
      Fix bug in union_lookup() (note: there are probably still several bugs
      in union_lookup()).  This one set lerror as a side effect without
      setting lowervp, causing copyup code further on down to crash on a null
      lowervp pointer.  Changed the side effect to use a temporary variable
      instead.
