In the same way than commit ae7487d112cf ("selftests/hid: ensure we can compile the tests on kernels pre-6.3") we should expose struct hid_bpf_ops when it's not available in vmlinux.h. So unexpose an eventual struct hid_bpf_ops, include vmlinux.h, and re-export struct hid_bpf_ops. Fixes: d7696738d66b ("selftests/hid: convert the hid_bpf selftests with struct_ops") Reported-by: kernel test robot <lkp@intel.com> Closes: https://lore.kernel.org/r/202406270328.bscLN1IF-lkp@intel.com/ Signed-off-by: Benjamin Tissoires <bentiss@kernel.org> --- Same situation than in an early report when HID-BPF was initially included: the automatically generated vmlinux.h doesn't contain all of the required structs and the compilation of the bpf program fails. --- tools/testing/selftests/hid/progs/hid_bpf_helpers.h | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) --- base-commit: d3e15189bfd4d0a9d3a7ad8bd0e6ebb1c0419f93 change-id: 20240627-fix-cki-f372855cbf6f Best regards,
