sg_init_table zeroes its first argument, so the allocation of that argument doesn't have to.
the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ expression x,n,flags; @@
x = - kcalloc + kmalloc_array (n,sizeof(*x),flags) ... sg_init_table(x,n) // </smpl>
