Description
When syseventd is terminated or restarted by svcadm, sometimes it will get stuck in waiting for exit of datalink notify thread.
It's found that the mutex and conditional variable are initialized after thread creation. If datalink notify thread runs into cond_wait() before initialization, it won't be waked up by cond_signal(). Then syseventd can't be stopped or restarted until force kill.
if (thr_create(NULL, 0, datalink_notify_thread, NULL, 0,
&dl_notify_tid) != 0) {
(void) rcm_free_handle(rcm_hdl);
return (NULL);
}
(void) mutex_init(&dl_mx, USYNC_THREAD, NULL);
(void) cond_init(&dl_cv, USYNC_THREAD, NULL);
