[PATCH bpf-next 0/3] bpf: Retire the unsupported_ops usage in struct_ops

[Martin KaFai Lau <martin.lau@linux.dev>]

From: Martin KaFai Lau <martin.lau@kernel.org>

This series retires the unsupported_ops usage and depends on the
null-ness check on the cfi_stubs instead.

Please see individual patches for details.

Martin KaFai Lau (3):
  bpf: Check unsupported ops from the bpf_struct_ops's cfi_stubs
  selftests/bpf: Fix the missing tramp_1 to tramp_40 ops in cfi_stubs
  selftests/bpf: Ensure the unsupported struct_ops prog cannot be loaded
