Beau,

Can you update the tools/testing/selftests/user_events/ to make sure that
it triggers the lockdep splat without these updates (assuming that it does
trigger without these patches). Then add these patches to make sure the
splat goes away. This will confirm that the patches do what is expected of
them.

I usually run the selftests for tracing and for your user events with
lockdep and prove locking enabled. But it may have triggered on something
else disabling it when I ran my tests, in which case I sometimes disable
that and forget to re-enable it.
