From 081363a22ecd72ea1287a4ff0b539ba536c1b646 Mon Sep 17 00:00:00 2001 From: Sabrina Dubroca Date: Wed, 4 Dec 2019 15:35:52 +0100 Subject: net: ipv6: add net argument to ip6_dst_lookup_flow commit c4e85f73afb6384123e5ef1bba3315b2e3ad031e upstream. This will be used in the conversion of ipv6_stub to ip6_dst_lookup_flow, as some modules currently pass a net argument without a socket to ip6_dst_lookup. This is equivalent to commit 343d60aada5a ("ipv6: change ipv6_stub_impl.ipv6_dst_lookup to take net argument"). Signed-off-by: Sabrina Dubroca Signed-off-by: David S.
