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
• bpf/bpf_core_read.h

Detected Declarations

• struct fake_kernel_struct
• function prog1
• function prog2
• function prog3

Annotation

• Immediate include surface: `vmlinux.h`, `bpf/bpf_helpers.h`, `bpf/bpf_tracing.h`, `bpf/bpf_core_read.h`.
• Detected declarations: `struct fake_kernel_struct`, `function prog1`, `function prog2`, `function prog3`.
• 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.
