Cellular Network Infrastructure » Core Network (CN) » OsmoMSC

While reading the source code, I've found that we have:

void on_dso_load_rrlp(void)
{
    osmo_signal_register_handler(SS_SUBSCR, subscr_sig_cb, NULL);
    osmo_signal_register_handler(SS_PAGING, paging_sig_cb, NULL);
}

but don't call it anywhere, according to `git grep on_dso_load_rrlp`:

include/osmocom/msc/rrlp.h:void on_dso_load_rrlp(void);
src/libmsc/rrlp.c:void on_dso_load_rrlp(void) { ... }
