Subject: [PATCH 02/10] intel: 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.

Subject: [PATCH 05/10] sfc: 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.

So you are able to confirm that all compilers make this assumption
correctly? The initial reason for using extern was because not all
compilers made the assumption or made it correctly.

You are probably thinking of global variables, where declarations
without either 'extern' or an initialiser might or might not be treated
as 'common'. On function declarations, 'extern' really is redundant.

No, I didn't bother.

Any current compilers already do make this assumption
valid as it's been part of the c spec since 1989 and
prototypes without extern already are the predominate
form in .h files for linux kernel sources.

Even in drivers/net/ethernet/intel/... there are more
prototypes without extern than with extern.

Furthermore, these networking headers include existing generic kernel
headers which already have removed the 'extern' from function
declarations in certain cases.

So I don't think there isn't an issue, and if there is it has existed
already for some time. :-)

Pulled, thanks Joe.
