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

• vmlinux.h
• bpf/bpf_helpers.h
• bpf/bpf_tracing.h

Detected Declarations

• struct bpf_testmod_ops
• function bss_array_sum
• function data_array_sum
• function BPF_PROG

Annotated Snippet

struct bpf_testmod_ops {
	int (*test_1)(void);
};

SEC(".struct_ops.link")
struct bpf_testmod_ops st_ops_resize = {
	.test_1 = (void *)test_1
};

Annotation

• Immediate include surface: `vmlinux.h`, `bpf/bpf_helpers.h`, `bpf/bpf_tracing.h`.
• Detected declarations: `struct bpf_testmod_ops`, `function bss_array_sum`, `function data_array_sum`, `function BPF_PROG`.
• 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.
