Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

• Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/atomic.h
• linux/cache.h
• thread-utils.h
• config.h
• indexer.h

Detected Declarations

• struct index_load_context
• struct uds_index_session
• enum index_suspend_status

Annotation

• Immediate include surface: `linux/atomic.h`, `linux/cache.h`, `thread-utils.h`, `config.h`, `indexer.h`.
• Detected declarations: `struct index_load_context`, `struct uds_index_session`, `enum index_suspend_status`.
• Atlas domain: Driver Families / drivers/md.
• 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.
