I haven't looked at this for a few months, but IIRC this is a circular
list.

Try using:
 for (next = tsk->next; next != tsk; next = next->next_task)

(this actually has a bug if there's only 1 process, but that's not going
to be a problem  :-)


Or if you'd rather start at tsk:
 next = tsk;
 do {
   /* ... */
 } while ((next = next->next_task) != tsk);
