       journal_forget - bforget for potentially-journaled buffers.


       int journal_forget  (handle_t * handle, struct buffer_head * bh);


       handle transaction handle

       bh     bh to ’forget’


       We  can only do the bforget if there are no commits pending against the
       buffer. If the buffer is dirty in the current  running  transaction  we
       can safely unlink it.

       bh  may  not be a journalled buffer at all - it may be a non-JBD buffer
       which came off the hashtable. Check for this.

       Decrements bh->b_count by one.

       Allow this call even if the handle has aborted --- it may  be  part  of
       the caller’s cleanup after an abort.
