For example, the following transformation:
- sizeof(s)-1
+ STRLEN(s)
would replace sizeof by STRLEN even in the STRLEN macro definition
itself, which generates following nonsensical patch:

* @x: a string literal.
*/
-#define STRLEN(x) (sizeof(""x"") - 1)
+#define STRLEN(x) (STRLEN("" x ""))
/*
* container_of - cast a member of a structure out to the containing structure
Let's exclude the macro itself from the transformation to avoid this
