  Modified files:        (Branch: RELENG_6)
    sys/ufs/ffs          ffs_snapshot.c ffs_vnops.c 
  Log:
  MFC: Close a race when VOP_LOCK() on a snapshot file is attempted at the
       same time as it is changed back into a normal file.  The locker would
       get the shared "snaplk" lock which would no longer be the correct lock
       for the vnode.
