Hi all
I'm not a C programmer and I have not spend much time reading the
kernel, but regarding my bug report I may have found the problem:
143 static void
144 propagate_priority(struct thread *td)
145 {
146 struct turnstile_chain *tc;
147 struct turnstile *ts;
148 struct thread *td1;
149 int pri;
150
151 mtx_assert(&sched_lock, MA_OWNED);
152 pri = td->td_priority;
153 ts = td->td_blocked;
154 for (;;) {
155 td = ts->ts_owner;
156
157 if (td == NULL) {
158 /*
159 * This really isn't quite right. Really
160 * ought to bump priority of thread that
161 * next acquires the lock.
162 */
163 return;
164 }
According to my first mail isn't td_blocked = 0x0? And wouldn't that
make line 155 fail?
