OK.
Now about the actual solution: what is your opinion on embedding e.g.
a squashfs image in the kernel instead, which would be a more generic
solution, not adding more ABI to /proc?
I'm not familiar enough with the

It's all in ease-of-use here. You want to build a trace function
against a running kernel, and now you have the header files for that
specific kernel right there in the kernel itself to build
