What is your problem Rob? I think message numbers are difficult to produce from format strings. I think kernel version/file/func/line is enough to identify messages for normal use but not too useful for embedded. I think losslessly compressing, not hashing, the format string would be useful. The format string would be expanded by printk. The kernel size would be smaller and more easily fit in minimal RAM. Losslessly compressing the format strings probably won't reduce flash image size. cheers, Joe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
