     tions to a persistent entity (such as a file) be discarded.

     The ID argument is the identity of  the  entity  to  revert.
     When  its  type  is  File, then the ID argument is unset (in
     other words, has a value of (char *)0), and it refers to the
     file or directory named in the message's file attribute.

     in processing the Revert notice:
