Coccinelle get confuse with kernel extern __printf macro for instance:
test.c:
extern __printf(3, 4)
int foo(int, int, char *, ...);
void toto(int, long);
test.sp:
@@
@@
void toto(int,
+void *,
long);
The semantic patch will not work. But if extern is remove or if __printf
macro is remove then it works. Also having extern and __printf on different
line make it works.
Cheers,
Jérôme

Maybe adding
#define __printf(a,b)
to standard.h will help?

Sorry to get back so late, yes adding #define __printf(a,b) to standard.h
solve the issue. Thank you for the pointer.
