From 49f8e8329c3c05e78a75112ce006c41d24eaad0d Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Thu, 8 Nov 2018 14:05:42 -0800 Subject: [PATCH] net: move __skb_checksum_complete*() to skbuff.c __skb_checksum_complete_head() and __skb_checksum_complete() are both declared in skbuff.h, they fit better in skbuff.c than datagram.c.
