[Nicolas Palix]

Here is a short excerpt of the semantic patch performing
this transformation:
(http://www.emn.fr/x-info/coccinelle/)

//<smpl>
@@
expression E1,E2,E3;

- kzalloc(E1*sizeof(E2),E3)
+ kcalloc(E1,sizeof(E2),E3)

@@
expression E1,E3;
type T;
@@
- kzalloc(E1*sizeof(T),E3)
+ kcalloc(E1,sizeof(T),E3)
