  SVN rev 193028 on 2009-05-29 10:02:44Z by des
  
  Let vfs_lookup() return ENOTDIR if the path has a trailing slash and
  the last component is a symlink to something that isn't a directory.
  
  We introduce a new namei flag, TRAILINGSLASH, which is set by lookup()
  if the last component is followed by a slash.  The trailing slash is
  then stripped, as before.  If the final component is a symlink,
  lookup() will return to namei(), which will expand the symlink and
  call lookup() with the new path.  When all symlinks have been
  resolved, lookup() checks if the TRAILINGSLASH flag is set, and if it
  is, and the vnode it ended up with is not a directory, it returns
  ENOTDIR.
