| |
From: Julia Lawall <julia@diku.dk>
kasprintf combines kmalloc and sprintf, and takes care of the size calculation itself.
The semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ expression a,flag; expression list args; statement S; @@
a = - \(kmalloc\|kzalloc\)(...,flag) + kasprintf(flag,args) <... when != a if (a == NULL || ...) S ...> - sprintf(a,args); // </smpl>
