  Modified files:
    sys/ufs/ufs          ufs_lookup.c 
  Log:
  The ufs_lookup.c has a critical bug around the whiteout
  process. UFS must check a whiteout name when it uses the
  whiteout, but the current implementation does not check
  the whileout name, so sometimes UFS writes over a wrong
  whtieout. UFS *MUST* check the whiteout name to use a
  corrent whiteout. This bug leads unionfs. panic.
  This commit fixes this trouble.
