From b4ac530fc3af02a004729043dacf6b6330b46892 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Tue, 10 Feb 2009 02:09:24 -0800 Subject: [PATCH] net: Move skbuff symbol exports after each symbol's definition. net/core/skbuff.c is a hodge-podge of symbol export placement. Some of the exports are right after the definition of the symbol being exported, others are clumped together into a big group at the end of the file. Make things consistent. Signed-off-by: David S.
