No problem, I'm happy to do this kind of exercise.  I like the API you
proposed.  I can do this change on top of the API change.  However,
since this bug is "in the wild" it may be applicable to stable@ as well.
 If you agree, I will also post v2 of this patch for stable kernels as
soon as we agree on the desired faulting behavior.
