Reduce log spam in journal

Feature request to reduce the journal spam - these messages are always duplicated and happen every minute or so:

rtkit-daemon[472050]: Supervising 0 threads of 0 processes of 0 users.
rtkit-daemon[472050]: Supervising 0 threads of 0 processes of 0 users.

I believe these lines are the culprit in rtkit-daemon.c:

-----rtkit-daemon.c line 1435 ------------------------

        syslog(LOG_DEBUG, "Supervising %u threads of %u processes of %u users.\n",
                n_total_threads,
                n_total_processes,
                n_users);

#ifdef HAVE_LIBSYSTEMD
        sd_notifyf(0,
                   "STATUS=Supervising %u threads of %u processes of %u users.",
                   n_total_threads,
                   n_total_processes,
                   n_users);
#endif
------------------------------

Would it be possible to patch these lines out? It appears they are purely DEBUG messages.
