On a related note, the patch creation process (of which klp-convert
would be part of) needs to be documented.

If I remember correctly, the proper safe usage of klp-convert requires a
kernel built with -flive-patching, plus some scripting and/or manual
processes.

If nobody knows how to safely use it then there wouldn't be much value
in merging it.
