Hook into kernel/exit.c to force exiting RT tasks into best-effort mode

Protect LITMUS^RT tasks from re-nicing

2014-10-21T14:08:01+00:00

Assigning a nice value to LITMUS^RT tasks is meaningless. Bail out
early.

Don't call set_tsk_need_resched() on remote LITMUS^RT task

2014-10-21T14:08:00+00:00

This patch fixes a BUG_ON() in litmus/preempt.c:33 reported by Felipe
Cerqueira & Manohar Vanga.

Hook into rt scheduling class to protect LITMUS^RT tasks

2014-10-21T14:07:40+00:00

The rt scheduling class thinks it's the highest-priority scheduling
class around. It is not in LITMUS^RT. Don't go preempting remote cores
that run SCHED_LITMUS tasks.

Don't trigger load balancer in scheduler tick for LITMUS^RT

Cache 'prev' in LITMUS^RT runqueue

2014-10-21T14:07:39+00:00

LITMUS^RT plugins like to know who 'prev' is. pick_next_task() doesn't
expose that info, so we just cache prev in the runqueue. Could robably
be replaced by looking at 'current' instead.

Hook into finish_switch()

2014-10-21T14:07:18+00:00

To keep track of stack usage and to notify plugin, if necessary.

Reset SCHED_LITMUS scheduling class on fork

Block sched_setaffinity() for SCHED_LITMUS tasks
