From cea80ea8d2a4c646f240a8fd6ece5c8e7bc969d3 Mon Sep 17 00:00:00 2001 From: Daniel Borkmann Date: Mon, 4 Nov 2013 17:10:25 +0100 Subject: net: checksum: fix warning in skb_checksum This patch fixes a build warning in skb_checksum() by wrapping the csum_partial() usage in skb_checksum(). The problem is that on a few architectures, csum_partial is used with prefix asmlinkage whereas on most architectures it's not. So fix this up generically as we did with csum_block_add_ext() to match the signature. Introduced by 2817a336d4d ("net: skb_checksum: allow custom update/combine for walking skb").
