It's no different than lockdep. Test boxes should have it enabled, but
there's no reason to have this enabled in a production system.
I tend to agree with Steven here (which is why I sent this patch as it
is), but I'm happy to do it as an opt-out, if Masami insists. Please
do let me know if I need to send v2 or this one is actually the one
we'll end up using. Thanks!
Masami,

Are you OK with just keeping it set to N.

We could have other options like PROVE_LOCKING enable it.
So what's the conclusion, Masami? Should I send another version where
this config is opt-out, or are you ok with keeping it as opt-in as
proposed in this revision?
