This will then work similarly as module kfunc registration in commit 3de4d22cc9ac ("bpf, btf: Warn but return no error for NULL btf from __register_btf_kfunc_id_set()") v5: - drop CONFIG_MODULE_ALLOW_BTF_MISMATCH check as Martin suggested. v4: - add a new patch to fix error checks for btf_get_module_btf. - rename the helper to check_btf_kconfigs. v3: - fix this build error: kernel/bpf/btf.c:7750:11: error: incomplete definition of type 'struct module' Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202402040934.Fph0XeEo-lkp@intel.com/ v2: - add register_check_missing_btf helper as Jiri suggested. ==================== Signed-off-by: Martin KaFai Lau --- a7170d81e0002345576b5f87a5890d91bc06c106
