Subject: [RFC][PATCH] Multimedia scheduling class

Hi,

I have created an experimental multimedia scheduling class (SCHED_MM)
for use with multithreaded non-hardcore-realtime multimedia
applications, such as ones based on gstreamer. These typically don't
follow the determinism rules of well behaved SCHED_FIFO applications.
However, these usually handle tasks like VoIP call audio processing,
where somewhat lower scheduling latency is needed to obtain good user
experience. Usually these are not very CPU-heavy and are mostly IO-bound
processes. Thus, something between normal SCHED_OTHER and SCHED_FIFO is
needed in a way where different threads of execution can set different
kinds of scheduling parameters.

I have attached an initial version of my experimental patch for comments...

Best regards,

	- Jussi Laako
