Why This File Exists

Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.

• Networking stack implementation surface: socket APIs, protocol dispatch, packet flow, routing, filtering, and network namespaces.
• 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/init.h
• linux/types.h
• linux/kernel.h
• linux/skbuff.h
• net/pkt_sched.h

Detected Declarations

• function blackhole_enqueue
• function blackhole_init
• module init blackhole_init

Annotation

• Immediate include surface: `linux/init.h`, `linux/types.h`, `linux/kernel.h`, `linux/skbuff.h`, `net/pkt_sched.h`.
• Detected declarations: `function blackhole_enqueue`, `function blackhole_init`, `module init blackhole_init`.
• Atlas domain: Networking Core / Sockets, Protocols, Packet Path, And Network Policy.
• 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.
