  Log:
  SVN rev 191260 on 2009-04-19 05:34:07Z by kib
  
  When verifying '..' after VFS_VGET() in ufs_lookup(), do not return
  error if '..' is still there but changed between lookup and check.
  Start relookup instead. Rename is supposed to change '..' reference
  atomically, so transient failures introduced by r191137 are wrong.
  
  While rearranging the code to allow lookup restart in ufs_lookup(),
  remove the comment that only distracts the reader.
