From: Joe Perches Date: Thu, 26 Sep 2013 21:48:15 +0000 (-0700) Subject: net.h/skbuff.h: Remove extern from function prototypes X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=7965bd4d71ef7cf1db00afb9e406ddfc13443c13;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git net.h/skbuff.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.
