Hi Paolo,
you once ask me to test your corrected rt_task_delete in the cvs. I did
not make it yet to that point, I was stopped by a more critical problem
showing up in the cvs but not in 3.1:
task_fun()
{
while (1) {
if (rt_sem_wait(&sem) == SEM_ERR)
return;
/* do some stuff */
}
}
init()
{
rt_typed_sem_init(&sem, 0, CNT_SEM);
rt_task_init(&task, task_fun, ...);
}
cleanup()
{
rt_sem_delete(&sem);
rt_task_delete(&task);
}
Gives some nice kernel crash, flodding my console without a chance to
see the first error.
Do you see an obvious reason for this? Or should I dig deeper? I think
something is terminated twice (1. by leaving task_fun, 2. by
rt_task_delete) without catching this special case.
Jan
PS: I know it is not a nice way to shut down (with respect to SMP), but
it is safe in our case because task_fun is known to block on the
semaphore on deletion.
