Ihor Solodrai	bd06b977e0	selftests/bpf: Migrate struct_ops_assoc test to KF_IMPLICIT_ARGS ... A test kfunc named bpf_kfunc_multi_st_ops_test_1_impl() is a user of __prog suffix. Subsequent patch removes __prog support in favor of KF_IMPLICIT_ARGS, so migrate this kfunc to use implicit argument.

Amery Hung	33a165f9c2	selftests/bpf: Test BPF_PROG_ASSOC_STRUCT_OPS command ... Test BPF_PROG_ASSOC_STRUCT_OPS command that associates a BPF program with a struct_ops. The test follows the same logic in commit ba7000f1c3 ("selftests/bpf: Test multi_st_ops and calling kfuncs from different programs"), but instead of using map id to identify a specific struct_ops, this test uses the new BPF command to associate a struct_ops with a program. The test consists of two sets of almost identical struct_ops maps and BPF programs associated with the map. Their only difference is the unique value returned by bpf_testmod_multi_st_ops::test_1(). The test first loads the programs and associates them with struct_ops maps. Then, it exercises the BPF programs. They will in turn call kfunc bpf_kfunc_multi_st_ops_test_1_prog_arg() to trigger test_1() of the associated struct_ops map, and then check if the right unique value is returned.
