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

• No C-style include directives detected by the generator.

Detected Declarations

• struct flow_key
• struct vip_definition
• struct vip_meta
• struct real_pos_lru
• struct real_definition
• struct lb_stats
• struct ctl_value
• function create_encap_ipv4_src
• function create_encap_ipv6_src

Annotation

• Detected declarations: `struct flow_key`, `struct vip_definition`, `struct vip_meta`, `struct real_pos_lru`, `struct real_definition`, `struct lb_stats`, `struct ctl_value`, `function create_encap_ipv4_src`, `function create_encap_ipv6_src`.
• 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.
