DESCRIPTION

14       The quorum_trackstart function is used to enable callbacks notification

17       Every time the voting configuration changes (eg a node joins  or  leave
18       the cluster) or the quorum status change, the notification is queued.

20       The notification is dispatched via quorum_dispatch() function that will
21       execute the callback.

24       and values can be bitwise-or'd
