 from the code:

  :   :
  : 
  : static __inline
  : off_t
  : tmpfs_dircookie(struct tmpfs_dirent *de)

  :         cookie = ((off_t)(uintptr_t)de >> 1) & 0x7FFFFFFF;
  :         KASSERT(cookie != TMPFS_DIRCOOKIE_DOT);
 
 This cookie scheme is clearly not workable.
 
 Why doesn't it just assign sequence numbers to each node or something?
