Hi Jaskaran,
Hi all,

I have noticed a regression in spatch since the recent SmPL improvements 
were merged. Here is a small reproducer:

@@
struct socket *sock;
struct sockaddr *uaddr;
int peer;
@@
{
+int ___addr_len;
...
- sock->ops->getname(sock, uaddr, peer);
+ sock->ops->getname(sock, uaddr, &___addr_len, peer);
...
}


This used to parse just fine, however now it errors out:


$ spatch --parse-cocci compat.cocci
init_defs_builtins: /usr/local/bin/../lib/coccinelle/standard.h
minus: parse error:
   File "compat.cocci", line 9, column 13, charpos = 98
   around = 'getname',
   whole content = - sock->ops->getname(sock, uaddr, peer);


I have bisected the problem and it appears that the first bad commit is:

commit c280375635f62dfbe052709e4e47a82140d32ce5

     Add parentypes to SmPL

     This allows the SmPL and C ASTs to better match up, which enables
     more transformations.  The patch is very large, so I have left
     the different messages as they were proposed in the original
     patch series.

Which is unfortunately huge, and since it was squashed together I really 
can't be any more specific.

Anyways, is this a bug? Or was I doing something wrong in the first place?

Thanks and best regards,
