Of course it will help, but the problem is not that. That patch helps
us to detect such a problem... I am still investigating. :-/

This looks like this is triggered by a write to a sysfs file,
so the solution is probably to call schedule_work so the
suspend can happen outside the context of sysfs.
The typical scenario that triggers this is:
- A lock is held while removing a sysfs attribute.
- The same lock is grabbed inside the sysfs attribute.
I think we do that with the cpu_hotplug.lock
In this case it looks like this might be a reach around scenario where
we try and remove the sysfs attribute that triggered the suspend.

Looking at this a bit more. Both this case and Arjuns (which is
completely different chain of events) seem to have in common people
removing sysfs attributes from within the contexts of a sysfs
attribute. As lockdep treats all instances of a lock as the same lock
it appears to be picking up false positives.
The classic mutex_lock_nested work around that introduces different lock
classes can not be used directly here as the code is too deeply nested.
The first problem this lockdep warning found was indeed a real and
subtle bug, I think there are several other real bugs this annotation
is capable of finding much easier than manual audits of the code, so I
don't want to remove the lockdep annotations.
Changing the cpu governor is especially interesting because it appears
that this coming from a sysfs attribute that will be removed if/when
the cpu is hotplug removed. Which says to me that we really would like
to have a couple of different lockdep classes in use, for essentially the
same lock.
So I think the thing to do is to add a lockdep subclass field to sysfs
attributes so that we can take teach lockdep to distinguish between
the handful of these that are safe because they are different instances
of the same lock.
How does the patch below look?

Subject: [PATCH] sysfs: Add support for lockdep subclasses to s_active
We have apparently valid cases where the code for a sysfs attribute
removes other sysfs attributes. Without support for subclasses
lockdep flags a possible recursive lock problem as it figures
the first sysfs attribute could be attempting to remove itself.
By adding support for sysfs subclasses we can teach lockdep to
distinguish between different types of sysfs attributes and not
get confused.

Hi Eric,
Is this the same locking problem that this patch fixes?

It certainly looks similar. The sysfs file that is being written
is different so I can't tell if that is a false positive because
sysfs is used for everything, or if it is a real issue.

Hmm. I tried your patch applied to a clean 2.6.33-rc4 tree, and used
the same .config file. This time the INFO looks a lot like my
original bug report. Weird. Maybe I am doing something wrong!

I agree weird. Either you don't have my patch working correctly or I
talk a good good game but I don't have a clue about lockdep
subclasses.
Grrr.
Now to see if I can find some time to dig into this. Thank you very
much for testing.

Subclasses and classes are basically the same thing, except that
subclasses are an 'easy' way to modify the regular class of an object.
Subclasses are limited to 7, 0 (the regular class), 1-7 subclasses.
Subclasses (just like regular classes) have no intrinsic ordering, their
order is given by the lock hierarchy.
Anything else you want to know?
