Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• bpf/libbpf.h
• test_progs.h
• network_helpers.h
• cb_refs.skel.h

Detected Declarations

• function test_cb_refs

Annotated Snippet

if (!ASSERT_OK_PTR(strstr(log_buf, cb_refs_tests[i].err_msg), "expected error message")) {
			fprintf(stderr, "Expected: %s\n", cb_refs_tests[i].err_msg);
			fprintf(stderr, "Verifier: %s\n", log_buf);
		}
		cb_refs__destroy(skel);
	}
}

Annotation

• Immediate include surface: `bpf/libbpf.h`, `test_progs.h`, `network_helpers.h`, `cb_refs.skel.h`.
• Detected declarations: `function test_cb_refs`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: source implementation candidate.

Implementation Notes

• This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
• Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
• Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
