often "kfree(NULL)", that is ok. it will let caller easier using it. also often give 0 size to snprintf, it still let caller easy using. if we treat EXPORT functions of kallsyms as commonly used (or we want to) I suggest to give parameter check for them. thanks. :-) -- Chen Gang Asianux Corporation -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
