How to use the pyfuse3.invalidate_inode function in pyfuse3

db.execute('UPDATE names SET refcount=refcount+1 WHERE id=?', (name_id,))

                    # Break every once in a while - note that we can't yield
                    # right here because there's an active DB query.
                    processed += 1
                    if processed > 200:
                        queue.append((src_id, target_id, name_id))
                        break

            await trio.hazmat.checkpoint()

        # Make replication visible
        self.db.execute('UPDATE contents SET parent_inode=? WHERE parent_inode=?',
                        (target_inode.id, tmp.id))
        del self.inodes[tmp.id]
        pyfuse3.invalidate_inode(target_inode.id)

        log.debug('finished')
