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.

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.

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.

This seems like a lot of code churn for very little benefit. At a quick
glance:
git grep extern include/ | wc -l
11427
Not all of those will need to be removed, but that is still a huge
number to change, and doesn't include extern usage in C files or local
headers. You are probably never going to remove all the instances, so
what is the point of just randomly doing a handful?

Rather more than a handful.
The ratio of function prototypes without extern to
function prototypes with extern is currently ~2.5:1
So:
Standardization without extern
Line count reduction (~10%)
Miscellaneous neatening at the same time
Removal of all unnecessary externs from include/net
There are ~8500 instances in include/
There are ~1500 instances in include/net/
After this series, 0 in include/net/
Start somewhere, go from there...
$ git grep -E "^\s*\bextern(\s+\w+){1,4}\s*\(\s*[^\*]" include/ | wc -l
8395
$ git grep -E "^\s*\bextern(\s+\w+){1,4}\s*\(\s*[^\*]" include/net/ | wc -l
1471

Right, and:
$ git grep -E "^\s*\bextern(\s+\w+){1,4}\s*\(\s*[^\*]" | wc -l
29104
Since there are lots of local/arch headers, and there are uses of extern
function prototypes in C files.
I don't see the real benefit though. Its like trying to "clean-up" the
difference between "unsigned x" and "unsigned int x", or any number of
other minor style differences. Either version, with or without the
extern, is correct, valid C code. Plus you will get people adding new
instances of extern because they don't know any better. A checkpatch
rule might help, but we all know how often people run that...
