Subject: Re: [PATCH] s390: move from strlcpy with unused retval to strscpy

Hi Alexander,

Sure. It is a bit hidden in $subject, but the key is to convert strlcpy
instances for now which do not check the return value. This is the
low-hanging fruit.

Converting the other uses checking the return value needs to be done
manually and much more carfully. I wanted to this as a second step, but
if you prefer to have everything converted in one go, I can give your
subsystem a priority boost. Would you prefer that?

Thanks and happy hacking,

   Wolfram
