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
