While at it, please introduce reverse xmas tree in variable
definitions incrementally:
struct lsmcontext context = { };
enum ip_conntrack_info ctinfo;
struct nfnl_ct_hook *nfnl_ct;
bool csum_verify;
u32 seclen = 0;
And Cc: netfilter-devel@vger.kernel.org for patches that update the
Netfilter codebase.
Thanks.
