Re: [PATCH v3 bpf-next 0/4] capture integers in BTF type info for map defs

This patch set implements an update to how BTF-defined maps are specified. The
change is in how integer attributes, e.g., type, max_entries, map_flags, are
specified: now they are captured as part of map definition struct's BTF type
information (using array dimension), eliminating the need for compile-time
data initialization and keeping all the metadata in one place.

All existing selftests that were using BTF-defined maps are updated, along
with some other selftests, that were switched to new syntax.

v2->v3:
- rename __int into __uint (Yonghong);
v1->v2:
- split bpf_helpers.h change from libbpf change (Song).

Andrii Nakryiko (4):
  libbpf: capture value in BTF type info for BTF-defined map defs
  selftests/bpf: add __int and __type macro for BTF-defined maps
  selftests/bpf: convert selftests using BTF-defined maps to new syntax
  selftests/bpf: convert legacy BPF maps to BTF-defined ones

Forgot to add Song's:

Acked-by: Song Liu <redacted>

Daniel, if there will be no more feedback, do you mind adding it
before landing? If not, I can submit new version with Acks added.

Thanks!
