Subject: [PATCH bpf-next 3/3] tools/bpf: add addition type tests to test_btf
The following additional unit testcases are added to test_btf:
BTF raw test[65] (typedef (invalid name, name_off = 0)): OK
BTF raw test[66] (typedef (invalid name, invalid identifier)): OK
BTF raw test[67] (ptr type (invalid name, name_off <> 0)): OK
BTF raw test[68] (volatile type (invalid name, name_off <> 0)): OK
BTF raw test[69] (const type (invalid name, name_off <> 0)): OK
BTF raw test[70] (restrict type (invalid name, name_off <> 0)): OK
BTF raw test[71] (fwd type (invalid name, name_off = 0)): OK
BTF raw test[72] (fwd type (invalid name, invalid identifier)): OK
BTF raw test[73] (array type (invalid name, name_off <> 0)): OK
BTF raw test[74] (struct type (name_off = 0)): OK
BTF raw test[75] (struct type (invalid name, invalid identifier)): OK
BTF raw test[76] (struct member (name_off = 0)): OK
BTF raw test[77] (struct member (invalid name, invalid identifier)): OK
BTF raw test[78] (enum type (name_off = 0)): OK
BTF raw test[79] (enum type (invalid name, invalid identifier)): OK
BTF raw test[80] (enum member (invalid name, name_off = 0)): OK
BTF raw test[81] (enum member (invalid name, invalid identifier)): OK
