Interesting. This structure is added in patch 1/17, then it's remove
in patch 15/17.

Probably I'm missing anything, but why are you doing it like that?

This structure means ctl_table_header,ctl_table and so on?

I add this structure to struct nf_proto_net in patch 1/17,so those fields in
struct nf_conntrack_l4proto are useless,this patch is just some cleanup.

the same with nf_conntrack_l3proto.

I see, then it's OK. Please, elaborate a bit more the patch
description to explain that this structure is not required anymore.
