Subject[PATCH] some kmalloc/memset ->kzalloc (tree wide)
Date

Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).

Here is a short excerpt of the semantic patch performing
this transformation:

@@
type T2;
expression x;
identifier f,fld;
expression E;
expression E1,E2;
expression e1,e2,e3,y;
statement S;
@@

x =

... when != \(x->fld=E;\|y=f(...,x,...);\|f(...,x,...);\|x=E;\|while(...) S\|for(e1;e2;e3) S\)
- memset((T2)x,0,E1);


@@
expression E1,E2,E3;

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