I've introduced a new get_strings() function that returns the possible strings stored in a pointer/array or &undefined if it's not-known. It's pretty crap because it only looks at strcpy() and not assignments and it's not cross function, but I'll add that stuff shortly. I added it to check_kernel_printf() in the laziest possible way just as a demo. I also changed how unions are handled to silence some false positives. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe smatch" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
