More easily written like this:

        QSIMPLEQ_FOREACH(aiocb, &s->io_q.pending, next) {
            if (s->io_q.in_flight + len >= MAX_EVENTS) {
                break;
            }
            iocbs[len++] = &aiocb->iocb;
        }

so that the early "if" is not necessary.  Also because you forgot the
braces around it. :)
