From a269fbfc4e9ffe48c1f8142e60a49b6f2e588c58 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 4 May 2020 10:06:04 +0200 Subject: xfrm: state: remove extract_input indirection from xfrm_state_afinfo In order to keep CONFIG_IPV6=m working, xfrm6_extract_header needs to be duplicated. It will be removed again in a followup change when the remaining caller is moved to net/xfrm as well.
