I poked around at the results of compiling with -Wformat-nonliteral, but gave up at trying to make it work. There are a number of clever uses of formats that would be hard to do otherwise. There are also several cases where a format string is used multiple times and we want to avoid repeating it. But using #define doesn't work, because we want to be able to translate it. I did find a little bit of low-hanging fruit, though. [1/2]: walker: let walker_say take arbitrary formats [2/2]: avoid using sha1_to_hex output as printf format These are totally independent of the main series, so they can be a separate topic, go on top, or just get dropped entirely if it's not worth the trouble. -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
