Related code in utrace_get_signal:
if (unlikely(report.killed)) {
/* COMMENT */
sigset_t sigkill_only;
siginitsetinv(&sigkill_only, sigmask(SIGKILL));
spin_lock_irq(&task->sighand->siglock);
signr = dequeue_signal(task, &sigkill_only, info);
BUG_ON(signr != SIGKILL);
*return_ka = task->sighand->action[SIGKILL - 1];
return signr;
}
The BUG_ON is triggered and I debug the signr value which is equal to 0, not
SIGKILL.
