As the functions have external linkage by default, the extern
keyword is irrelevant here.

extern is used to say that the storage of a variable is done
somewhere else.  It marks a statement as a declaration when
there is ambiguity about if the statement is a definition or
declaration.  Since function prototypes are not definitions,
extern doesn't have any effect on them.  It is not really
related to linkage or scope.

Regardless, this patch doesn't apply.
