>Description:
The behavior of SCHED_FIFO threads doesn't match the specification.
Quote:
--
When a running thread becomes a preempted thread, it becomes the head of the thread list for its priority.
--
NetBSD currently does the opposite. It would be good to verify some of
the other requirements are met.
>How-To-Repeat:
Read the spec:
http://www.opengroup.org/onlinepubs/007908799/xsh/realtime.html
I won't cut and paste it here, but see the section with header
SCHED_FIFO.
>Fix:
Match spec.
