It's not a 2 byte binary. It's a leading ascii SOH and a standard ascii char '0' ... '7' or 'd'. #define KERN_EMERG KERN_SOH "0" /* system is unusable */ #define KERN_ALERT KERN_SOH "1" /* action must be taken immediately */ etc... > And if that changes the log-level to "2" instead of the default "4"? No it doesn't. It's not triggering that because devkmsg_writev does prefix parsing only on the old "<n>" form. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
