Hi,

I'm getting the page fault below everytime during bootup. This is how 
__task_rq_lock looks like:
         for (;;) {
                 struct rq *rq;
         printk("CPU=%u %p %p %p %s\n", task_cpu(p), p,
                         task_thread_info(p)->task,
                         task_thread_info(p), p->comm);
                 rq = task_rq(p);
                 spin_lock(&rq->lock);
                 if (likely(rq == task_rq(p)))
                         return rq;
                 spin_unlock(&rq->lock);
         }

It'd be useful to know if bare linux-next does the same thing, please.

Not present at d6b658c (which is one from the mmotm), so this is pure 
-mm thing. Something between 2009-02-14-00-49 and this one.

This hunk fixes the problem for me. I have no idea if it is correct though.

hm, it does seem to forget to initialise ->result on the success path.

Someone else has been mucking with kthread.c in linux-next, and a
couple of days ago that mucking got dropped from linux-next.  Perhaps
this churn broke Oleg's patch.

And if it was Stephen who dropped the offending tree, that mucking
about will come back soon and will re-muck things up.

<checks>

	Undropped tree:
		rr

And what does that do?  yup,

guys, please stop mucking things up?

Err, yes.

Oleg and I had an accidentally-offlist chat about these patches.

Last we decided, a more ambitious approach was desired.  Patches RSN.

I've taken kthreads-move-sched-realeted-initialization-from-kthreadd-context.patch
though, thanks!

Cheers,
Rusty.

"[merged] kthread-dont-looking-for-a-task-in-create_kthread-2.patch"
has "create->result = current;" in kthread(), then this line was
lost somehow,

Yes, but can't we do this on top of current patches?

We are going to change the API a bit, so that kthread_create() bumps
a reference to task_struct. I think it would be nice to separate the
API changes from the implementation changes.

Oleg.

So, what happened with

	kthreads-simplify-the-startup-synchronization.patch
	http://marc.info/?l=linux-mm-commits&m=123335224710768

	kthreads-rework-kthread_stop.patch
	http://marc.info/?l=linux-mm-commits&m=123335227910835

patches? Can't find them in any tree.

Oleg.

I seem to have had an administrative error.  I think the patches were
temporarily parked because people were madly changing things under my feet,
and they didn't get unparked.

I've just restored

kthreads-simplify-the-startup-synchronization.patch
kthreads-rework-kthread_stop.patch
kthreads-simplify-migration_thread-exit-path.patch

and I'll send them out again.

I hope nothing else got lost.  They're the only *kthread* patches which
I can see here.

Thanks!

Yes, there was nothing else kthread-related.

Is there any CONFIG_ symbol associated with $subject sysctl?

'one' is only available (currently) when:

#if defined(CONFIG_DETECT_HUNG_TASK) || defined(CONFIG_DETECT_SOFTLOCKUP) || defined(CONFIG_HIGHMEM)
static int one = 1;
#endif

so it gives us
kernel/sysctl.c:1067: error: 'one' undeclared here (not in a function)

when one of those is not #defined.
