Alexei Starovoitov 63260df139 bpf: Refactor btf_nested_type_is_trusted(). ... btf_nested_type_is_trusted() tries to find a struct member at corresponding offset. It works for flat structures and falls apart in more complex structs with nested structs. The offset->member search is already performed by btf_struct_walk() including nested structs. Reuse this work and pass {field name, field btf id} into btf_nested_type_is_trusted() instead of offset to make BTF_TYPE_SAFE*() logic more robust.
