Silly question for you that is more about the original code than what you
are adding, but why the casts?  It is already a const pointer so I think
we are fine under the C spec to just do this cast implicitly to a const
void *

If you agree, ideally please add a precursor patch to drop these casts
before this patch.

Thanks,

Jonathan
