From 903922cfa0e60573234ff895974c23a000035258 Mon Sep 17 00:00:00 2001 From: Ihor Solodrai Date: Fri, 19 Dec 2025 10:18:23 -0800 Subject: lib/Kconfig.debug: Set the minimum required pahole version to v1.22 Subsequent patches in the series change vmlinux linking scripts to unconditionally pass --btf_encode_detached to pahole, which was introduced in v1.22 [1][2]. This change allows to remove PAHOLE_HAS_SPLIT_BTF Kconfig option and other checks of older pahole versions.
