Why This File Exists
Rust-side wrappers and abstractions around kernel C APIs, ownership contracts, allocation, synchronization, and module integration.
- Rust-side wrappers and abstractions around kernel C APIs, ownership contracts, allocation, synchronization, and module integration.
- Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

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.
