Add missing kernel-doc documentation for the cfi_stubs and owner fields in struct bpf_struct_ops to fix the following warnings: Warning: include/linux/bpf.h:1931 struct member 'cfi_stubs' not described in 'bpf_struct_ops' Warning: include/linux/bpf.h:1931 struct member 'owner' not described in 'bpf_struct_ops' The cfi_stubs field was added in commit 2cd3e3772e41 ("x86/cfi,bpf: Fix bpf_struct_ops CFI") to provide CFI stub functions for trampolines, and the owner field is used for module reference counting. Signed-off-by: Nirbhay Sharma --- Changes in v2: - Removed documentation for non-existent fields (type, value_type, type_id, value_id) that were moved to bpf_struct_ops_desc in commit 4c5763ed996a include/linux/bpf.h | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/include/linux/bpf.h b/include/linux/bpf.h index d808253f2e94..96851fa0494f 100644 --- a/include/linux/bpf.h +++ b/include/linux/bpf.h @@ -1905,12 +1905,14 @@ struct btf_member; * reason, if this callback is not defined, the check is skipped as * the struct_ops map will have final verification performed in * @reg. - * @type: BTF type. - * @value_type: Value type. + * @cfi_stubs: Pointer to a structure of stub functions for CFI.
