As discussed in the previous thread, the coccinelle rules and some 
replacements will be added in the future.

Thanks,

Then we have to wait for this one until then.  Remember, we can not take
functions that no one calls, as they will be noticed and someone will
remove them.

Please make a patch series with the function being used, that's the only
way we can actually determine if the addition is correct or not.

thanks,
