This is part 4 of https://lore.kernel.org/bpf/20230123232228.646563-1-void@xxxxxxxxxxxxx/ Part 3: https://lore.kernel.org/all/20230125050359.339273-1-void@xxxxxxxxxxxxx/ Part 2: https://lore.kernel.org/all/20230124160802.1122124-1-void@xxxxxxxxxxxxx/ Changelog: ---------- v3 -> v4: - Fix accidental typo in name of dummy_st_ops introduced in v2, moving it back to dummy_st_ops from dummy_st_ops_success. Should fix s390x testruns. v2 -> v3: - Don't call a KF_SLEEPABLE kfunc from the dummy_st_ops testsuite, and remove the newly added bpf_kfunc_call_test_sleepable() test kfunc (Martin). - Include vmlinux.h from progs/dummy_st_ops_success.c (previously progs/dummy_st_ops.c) rather than manually defining struct bpf_dummy_ops_state and struct bpf_dummy_ops. (Martin). - Fix a typo added to prog_tests/dummy_st_ops.c in a previous version: s/trace_dummy_st_ops_success__open/trace_dummy_st_ops__open. v1 -> v2: - Add support for specifying sleepable struct_ops programs with struct_ops.s in libbpf (Alexei). - Move failure test case into new dummy_st_ops_fail.c prog file. - Update test_dummy_sleepable() to use struct_ops.s instead of manually setting prog flags. Also remove open_load_skel() helper which is no longer needed. - Fix verifier tests to expect new sleepable prog failure message.
