From 3e50ddd8b8d5067796fc87cbbb25c71451ccb385 Mon Sep 17 00:00:00 2001 From: Florian Westphal Date: Mon, 4 May 2020 10:06:06 +0200 Subject: xfrm: expose local_rxpmtu via ipv6_stubs We cannot call this function from the core kernel unless we would force CONFIG_IPV6=y. Therefore expose this via ipv6_stubs so we can call it from net/xfrm in the followup patch. Since the call is expected to be unlikely, no extra code for the IPV6=y case is added and we will always eat the indirection cost.
