Dumping internal tables and information via /procfs is strongly
deprecated.

Please use a more modern mechanism (such as netlink) to expose this
information to the user.

You'll be most likely to succeed in your submission if you make use of
or design a generic facility that allows other drivers similar to
your's to provide this kind of information as well.

I'm sorry if this is frustrating, but this is a huge piece of
infrastructure, therefore you can expect lots of pieces to get
feedback and require changes like this.
