Hi all, This series allows CONFIG_DEBUG_INFO_DWARF5 to be selected with CONFIG_DEBUG_INFO_BTF=y by checking the pahole version. The first four patches add CONFIG_PAHOLE_VERSION and scripts/pahole-version.sh to clean up all the places that pahole's version is transformed into a 3-digit form. The fourth patch adds a PAHOLE_VERSION dependency to DEBUG_INFO_DWARF5 so that there are no build errors when it is selected with DEBUG_INFO_BTF. I build tested Fedora's aarch64 and x86_64 config with ToT clang 14.0.0 and GCC 11 with CONFIG_DEBUG_INFO_DWARF5 enabled with both pahole 1.21 and 1.23.
