Perhaps this is good enough? cp scripts/coccinelle/api/alloc/kzalloc-simple.cocci scripts/coccinelle/api/alloc/vzalloc-simple.cocci sed -i -e 's/kmalloc/vmalloc/g' -e 's/kzalloc/vzalloc/g' scripts/coccinelle/api/alloc/vzalloc-simple.cocci -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
