So when exactly is it useful?

If I understand correctly, there are no users of this code in
mainline.  Should the patch then not be part of a patch series that
adds such users?

Adding potentially "useful" code just on speculation is not nice
maintenance-wise.

I recommend to withdraw this patch and submit it together with some
real consumer of this feature.

Thanks.

Best regards,

Wolfgang Denk
