The freeque() implementation must wait until all waiting reader threads have left the kernel: > while (waitqueue_active(&msq->rwait) || waitqueue_active(&msq->wwait)) { > wake_up (&msq->rwait); > wake_up (&msq->wwait); > schedule(); > }
I've read that calling schedule() could lock up. What's the exact problem? (I read that it has something to to with SCHED_RR threads).
