Subject[PATCH bpf-next v2 0/4] Enable struct_ops programs to be sleepable
Date
This is part 2 of https://lore.kernel.org/bpf/20230123232228.646563-1-void@manifault.com/

Changelog:
----------
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.

David Vernet (4):
bpf: Allow BPF_PROG_TYPE_STRUCT_OPS programs to be sleepable
libbpf: Support sleepable struct_ops.s section
bpf: Pass const struct bpf_prog * to .check_member
bpf/selftests: Verify struct_ops prog sleepable behavior
