commit f685ceacab07d3f6c236f04803e2f2f0dbcc5afb
Author: Mike Galbraith <efault@gmx.de>

sched: Strengthen buddies and mitigate buddy induced latencies
This patch restores the effectiveness of LAST_BUDDY in preventing
pgsql+oltp from collapsing due to wakeup preemption. It also
switches LAST_BUDDY to exclusively do what it does best, namely
mitigate the effects of aggressive wakeup preemption, which
improves vmark throughput markedly, and restores mysql+oltp
scalability.

hm, the problem is kthread_bind(). It is rummaging around in scheduler
internals without holding the runqueue lock - and this now got exposed.
Even though it is operating on (supposedly ...) inactive tasks, the guts
of that function should be moved into sched.c and it should be fixed to
have proper locking.

Yeah, I was thinking that nobody should ever be able to hit that without
it being a bug.. but wimped out.

How about so?

Now if I just knew why -next kernels under kvm seem to randomly corrupt

Oops. Outside the SMP block might work a little better.
sched: Move the body of kthread_bind() to sched.c.
Eric Paris reported that commit f685ceacab07d3f6c236f04803e2f2f0dbcc5afb
causes boot time PREEMPT_DEBUG complaints.

Since kthread_bind() messes with scheduler internals, move the body to sched.c,
and lock the runqueue.

Check the -tip commit notification, i did a somewhat cleaner approach by
moving all of kthread_bind() into sched.c. No need to keep that small
wrapper in kthread.c.

Mike Galbraith's patch didn't work.
There is something with scheduler.

I think we may have a problem. It appears to me that selecting runqueue
without holding the runqueue lock is still unsafe wrt migration.
One problem I see is that we were doing set_task_cpu() without the lock
held, what the kthread_bind() patch fixed. However, fixing that did..
not much at all.
Probably because once we release the lock, we can be preempted. Lots of
the things we're looking at can change underneath us without that lock
held. Anyway below is what I think is proof that this is indeed unsafe.
Virgin source running netperf UDP_STREAM _doubles_ throughput with only
1b9508f applied. No way in hell that patch can do that. It needs some
serious help. Like maybe using more than the two CPUs assigned, running
this and that all over the box (but too fast to _see_ in top)?
sched: restore runqueue locking during runqueue selection.
Selecting runqueue with the runqueue unlocked is not migration safe,
restore old locking.

BTW, with (only) the full scheduler pull request applied, it also acts
sane, and this little hunk is responsible... somehow. But if that's the
problem, why does locking the runqueue fix it too??

A bit of late night cut/paste fixed it right up, so tomorrow, I can redo
benchmarks etc etc.
Lai, mind giving this a try? I believe this will fix your problem as
well as mine.
sched: fix runqueue locking buglet.
Calling set_task_cpu() with the runqueue unlocked is unsafe. Add cpu_rq_lock()
locking primitive, and lock the runqueue. Also, update rq->clock before calling
set_task_cpu(), as it could be stale.
Running netperf UDP_STREAM with two pinned tasks with tip 1b9508f applied emitted
the thoroughly unbelievable result that ratelimiting newidle could produce twice
the throughput of the virgin kernel. Reverting to locking the runqueue prior to
runqueue selection restored benchmarking sanity, as finally did this patchlet.

My problem: a bound task is run on a different cpu. You haven't describe

That's an easy one. I haven't figured out exactly how it happens, made
8x10 color glossies with circles and arrows etc, but read on anyway.
My problem is bound tasks doubling their throughput. How do they do
that while staying bound to CPUs that do not share a cache? If I make a
shortcut in select_rq() for bound tasks, so we don't waste time looking
for a place to put a pinned task, why does throughput decrease? I
haven't made film and analyzed it, but that's what is happening. We are
diddling the task struct with zero protection, and that is causing the
bad thing to happen, which is what I care about.
Now that I've fixed the problem, here's the throughput of the same
netperf run when bound to cache affine CPUs.

Process p is being held hostage by TASK_WAKING. It's going nowhere but
where select_task_rq() tells us to put it, and that's the runqueue we
must lock. If you lock p's old runqueue, and it's not the runqueue
you're about to queue it to, nothing good is gonna happen.
In fact, now that I think about it more, seems I want to disable preempt
across the call to select_task_rq(). Concurrency sounds nice, but when
when waker is preempted, the hostage, who may well have earned the right
to instant cpu access will wait until the waker returns, and finishes
looking for a runqueue. We want to get wakee onto the runqueue asap.
What happens if say a SCHED_IDLE task gets CPU on a busy box long enough
to wake kjournald?

No, that's not the garbage bit. The true hazard of late late night is
that you can't _see_ anymore. cpu_rq_lock + spin_unlock :)))))
Now I'm _really_ puzzled. Embarrassing, but funny.

So, here's the 6 A.M. no java yet version. Now to go _make_ some java,
and settle in for a long test session.
sched: fix runqueue locking buglet.
Calling set_task_cpu() with the runqueue unlocked is unsafe. Add cpu_rq_lock()
locking primitive, and lock the runqueue. Also, update rq->clock before calling
set_task_cpu(), as it could be stale.
Running netperf UDP_STREAM with two pinned tasks with tip 1b9508f applied emitted
the thoroughly unbelievable result that ratelimiting newidle could produce twice
the throughput of the virgin kernel. Reverting to locking the runqueue prior to
runqueue selection restored benchmarking sanity, as did this patchlet.

Hi -
I have same oops (different cause-vector). Details here http://lkml.org/lkml/2009/11/23/548
Can anyone tell me if they are related and/or recommend any work-arounds or troubleshooting steps?
Could this be related to scheduler trying to reschedule a task/thread on other proc and possibly a false alarm?
Snip from trace is below.

Which is an -rt kernel and very likely totally unrelated.

No, the warning says you try to get the current cpu number when the code
in question is in no way tied to a particular cpu, therefore the cpu
number obtained is totally useless.
> and possibly a false alarm?
Most likely not.
Look at your particular source-tree and try to fine the
smp_processor_id() call that triggers this, then look what it needs the
cpu number for and fix the code so that it makes sense ;-)
