After considering Linus's recent feedback on kernel configuration complexity, I'm reconsidering this approach. He recently emphasized: "The kernel config phase is probably one of the biggest pain points for random new people trying to build their own kernels, and we DO NOT ASK PEOPLE STUIPID THINGS." --Linus https://lore.kernel.org/all/CAHk-=whigg3hvOy7c1j1MXFy6o6CHp0g4Tc3Y-MAk+XDssHU0A@mail.gmail.com/ I will respin a new version, dropping this patch from the series to keep Linus’ blood pressure in check. --breno
