[Cocci] iterator and single line statement

[Corentin Chary]

Hi,
I'm trying to do a patch to replace list_for_each_entry with
ulist_for_each_entry (don't ask why, it's ugly).

Here is my patch:

@@
iterator name list_for_each_entry;
iterator name ulist_for_each_entry;
statement S;
type T;
T *a;
expression b, c;
@@

- list_for_each_entry(a, b, c)
+ ulist_for_each_entry(a, b, c, T)
  S

@@
iterator name list_for_each_entry_safe;
iterator name ulist_for_each_entry_safe;
statement S;
type T;
T *a;
expression b, c;
@@

- list_for_each_entry_safe(a, b, c)
+ ulist_for_each_entry_safe(a, b, c, T)
  S

With a single line statement it produce :
        spin_lock(&c->buds_lock);
        for (i = 0; i < c->jhead_cnt; i++)
-               list_for_each_entry(bud, &c->jheads[i].buds_list, list)
+               {ulist_for_each_entry(bud, &c->jheads[i].buds_list,
list, struct ubifs_bud)
                        bud_bytes += c->leb_size - bud->start;
+               }


Is it a bug in coccinelle, or my patch is not ok ?

Thanks
