    Date
    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
