It is the same path perf tool is taking - see first paragraph: https://lore.kernel.org/r/YtQM40VmiLTkPND2@kernel.org I don't want to deal with the regular breakages or hacks to boot/compressed/ just because little duplication. We copy the header once and that's it - it doesn't even have to get updated like perf tool does from time to time. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette
