sched: rework of "prioritize non-migratable tasks over migratable ones"
(1) handle in a generic way all cases when a newly woken-up task is not migratable (not just a corner case when "rt_se->nr_cpus_allowed == 1") (2) if current is to be preempted, then make sure "p" will be picked up by pick_next_task_rt(). i.e. move task's group at the head of its list as well. currently, it's not a case for the group-scheduling case as described here: http://www.ussg.iu.edu/hypermail/linux/kernel/0807.0/0134.html Signed-off-by: Dmitry Adamushko <dmitry.adamushko@gmail.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Gregory Haskins <ghaskins@novell.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
