From 3cc818a27d17fc57aa37ee89d09feb2bc2dd789f Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sat, 21 Sep 2013 10:22:47 -0700 Subject: [PATCH] ndisc.h: Remove extern from function prototypes There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block. Signed-off-by: Joe Perches Signed-off-by: David S.
