  Log:
  SVN rev 212664 on 2010-09-15 15:33:51Z by mdf
  
  Revert r212563, which was a MFC of r209053, as it introduced an unlocked
  read/modify/write of b_vflags.  The unlocked access is fixed in CURRENT
  and stable/8 by r211213 and its MFC, r212583.
  
  Rather than MFC to stable/7, reverting the injecting code seems
  preferable.
