KConfig: disable module BTF debug info enabling this effectively makes the debug info of the kernel image part of the kernel <-> module ABI[0], potentially breaking module loading for otherwise compatible kernel/module combinations. there were several user reports[1,2,3,..], and although a workaround exists (re-installing the currently booted version, loading the module, then upgrading again) disabling this until it's clear how to proceed seems like the way to go. disabling via patch is needed, since leaving it unset via `-d` or explicitly disabled via `--set-val` doesn't work - it's auto-enabled based on build-env pahole supporting split BTF generation. 0: https://lore.kernel.org/all/1637926692.uyvrkty41j.astroid@nora.none/ 1: https://forum.proxmox.com/threads/realtek-8156-2-5gbe-usb-nic.69903/#post-433793 2: https://forum.proxmox.com/threads/usb-storage-can-not-be-mounted.100480/ 3: https://forum.proxmox.com/threads/neuer-server-und-probleme.99098/#post-427862 Signed-off-by: Fabian Grünbichler <f.gruenbichler@proxmox.com> Acked-by: Thomas Lamprecht <t.lamprecht@proxmox.com> Reviewed-by: Thomas Lamprecht <t.lamprecht@proxmox.com>
