Hi Fengguang, I also check new static checker warnings and sometimes email people. I wonder if we are duplicating each others work. For example, did you send an email asking about the following Sparse warning: sound/soc/codecs/ab8500-codec.c:1959:53: warning: cast truncates bits from constant value (1013 becomes 13) Quite often those messages are false positive and the value is truncated deliberately. In this case it looks suspicious and I would maybe email about it. If I knew what kind of messages you check and which you ignore that would help me. Perhaps there is an email list I could subscribe to to see if you had already sent a message. regards, dan carpenter -- To unsubscribe from this list: send the line "unsubscribe kernel-janitors" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
