[PATCH 0/5] sched: misc rt fixes for tip/sched/devel

[Gregory Haskins]

Hi Ingo,

The following repositories

     git://git.kernel.org/pub/scm/linux/kernel/git/ghaskins/linux-2.6-hacks.git tip/sched/devel/rtbalance 

     ftp://ftp.novell.com/dev/ghaskins/tip-rt-fixes.tar.bz2

apply to tip/sched/devel to pick up the following fixes for the RT
scheduler. 

---

Gregory Haskins (5):
      sched: create "pushable_tasks" list to limit pushing to one attempt
      sched: add sched_class->needs_post_schedule() member
      sched: make double-lock-balance fair
      sched: pull only one task during NEWIDLE balancing to limit critical section
      sched: only try to push a task on wakeup if it is migratable

These patches were developed in the interest of shorting latencies in
PREEMPT_RT, but they apply to the mainline scheduler as well, so I am
offering them here first.

This has been tested under both 26.3-rt3 and tip/sched/devel on x86_64 for
both CONFIG_SMP and !CONFIG_SMP.

Comments/bug-fixes welcome!

Regards,
-Greg
