Why This File Exists
Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

Annotation
- Immediate include surface: `linux/mutex.h`, `linux/pid_namespace.h`, `rdma/restrack.h`, `rdma/rdma_netlink.h`.
- Detected declarations: `struct ib_device`, `struct ib_qp`, `struct auto_mode_param`, `struct rdma_counter_mode`, `struct rdma_port_counter`, `struct rdma_counter`.
- Atlas domain: Repository Root And Misc / include.
- 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.
