Most of the kernel messages would be intended to know developers what's going on in the kernel, and they tend to be not friendly to users and machines. To improve this, Hidehiro Kawai is trying to add hash value for each kernel message to identify them easily. If this feature becomes available, users can consult external manuals by feeding the hash and know detailed information. Or a monitor tool can identify specific message in low overhead and trigger a fail-over or collect related information automatically. In this presentation, he explains the implementation of the first RFC patch set, on-going discussions (if there are), and how utilizing the feature in user space, while introducing a similar challenge 5 years ago and how addressed its objections.
