The Linux kernel coding style guidelines suggest not using typedefs
for structure types. This patch gets rid of the typedef for
local_info_t. Also, the name of the struct is changed to drop the _t,
to make the name look less typedef-like.
The following Coccinelle semantic patch detects the case:
@tn@
identifier i;
type td;
@@
-typedef
struct i { ... }
-td
;
@@
type tn.td;
identifier tn.i;
@@
-td
+ struct i
