selftests/bpf: Test parsing of (multi-)split BTF

2025-11-04T21:44:12+00:00

Write raw BTF to files, parse it and compare to original;
this allows us to test parsing of (multi-)split BTF code.

selftests/bpf: Test multi-split BTF

2025-05-20T23:22:30+00:00

Extend split BTF test to cover case where we create split BTF on top of
existing split BTF and add info to it; ensure that such BTF can be
created and handled by searching within it, dumping/comparing to expected.
