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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/bpf.h
• linux/btf.h
• linux/init.h
• linux/module.h

Detected Declarations

• struct bpf_test_no_cfi_ops
• function dummy_init
• function dummy_init_member
• function dummy_reg
• function dummy_unreg
• function bpf_test_no_cfi_ops__fn_1
• function bpf_test_no_cfi_init
• function bpf_test_no_cfi_exit
• module init bpf_test_no_cfi_init

Annotation

• Immediate include surface: `linux/bpf.h`, `linux/btf.h`, `linux/init.h`, `linux/module.h`.
• Detected declarations: `struct bpf_test_no_cfi_ops`, `function dummy_init`, `function dummy_init_member`, `function dummy_reg`, `function dummy_unreg`, `function bpf_test_no_cfi_ops__fn_1`, `function bpf_test_no_cfi_init`, `function bpf_test_no_cfi_exit`, `module init bpf_test_no_cfi_init`.
• Atlas domain: Support Tooling And Documentation / tools.
• Implementation status: integration 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.
