Hook into rt scheduling class to protect LITMUS^RT tasks 2013-08-07T07:47:02+00:00 Bjoern Brandenburg bbb@mpi-sws.org 2013-07-01T21:56:31+00:00 1288313c31e75a5138e4c87901eda10a07ee80ca 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.

LITMUS^RT plugins like to know who 'prev' is. pick_next_task() doesn't
