OK, let me try that, however, see below.

That looks like the lockdep_assert_held(&lock->wait_lock) in
__ww_mutex_wakeup_for_backoff().
That should be solved the below commit, which is also present in both
mainline and -next.

locking/mutex: Fix lockdep_assert_held() fail
In commit:
659cf9f5824a ("locking/ww_mutex: Optimize ww-mutexes by waking at most one waiter for backoff when acquiring the lock")
I replaced a comment with a lockdep_assert_held(). However it turns out
we hide that lock from lockdep for hysterical raisins, which results
in the assertion always firing.
Remove the old debug code as lockdep will easily spot the abuse it was
meant to catch, which will make the lock visible to lockdep and make
the assertion work as intended.

In test-ww_mutex, the stress will use 4096 locks to do the test, and
given held_lock::references only have 12 bits, so I think this is the
reason? I made a patch to reduce the lock number of stress test, and it
seems the problem is resolved.
Thoughts?

Subject: [PATCH] locking/ww_mutex: Adjust the lock number for stress test
Because there are only 12 bits in held_lock::references, so we only
support 4095 nested lock held in the same time, adjust the lock number
for ww_mutex stress test to kill one lockdep splat:

Aaaahhh!! YES. I completely overlooked (and forgot) ww_mutex used that.
Let me also do a lockdep patch that complains on overflow there.

commit b9c16a0e1f733c97e48798b2a9362c485bb3b731
Author: Peter Zijlstra <peterz@infradead.org>

locking/mutex: Fix lockdep_assert_held() fail
In commit:
659cf9f5824a ("locking/ww_mutex: Optimize ww-mutexes by waking at most one waiter for backoff when acquiring the lock")
I replaced a comment with a lockdep_assert_held(). However it turns out
we hide that lock from lockdep for hysterical raisins, which results
in the assertion always firing.
Remove the old debug code as lockdep will easily spot the abuse it was
meant to catch, which will make the lock visible to lockdep and make
the assertion work as intended.

So with all the various patches it works for me.
I also have the following on top; which I did when I was looking through
this code trying to figure out wth was happening.
Chris, does this make sense to you?
It makes each loop a fully new 'instance', otherwise we'll never update
the ww_class->stamp and the threads will aways have the same order.

Sounds ok, I just thought the stamp order of the threads was
immaterial - with each test doing a different sequence of locks and each
being identical in behaviour, it would not matter which had priority,
there would have be some shuffling no matter waht. However, for the
purpose of testing, having each iteration be a new locking instance does
make it behaviour more like a typical user.

Correcting myself, the workers didn't reorder the locks, so changing the
stamp does make the test more interesting.

OK, so I'll go write a Changelog for it then ;-) And stick your ACK on.

With both patches in this thread, all 110 boots are successful w/o a
single warning.

locking/ww_mutex: Adjust the lock number for stress test
Because there are only 12 bits in held_lock::references, so we only
support 4095 nested lock held in the same time, adjust the lock number
for ww_mutex stress test to kill one lockdep splat:
[ ] [ BUG: bad unlock balance detected! ]
[ ] kworker/u2:0/5 is trying to release lock (ww_class_mutex) at:
[ ] ww_mutex_unlock()
[ ] but there are no more locks to release!
