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

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

Detected Declarations

• struct dm_dev
• struct dm_path

Annotated Snippet

struct dm_path {
	struct dm_dev *dev;	/* Read-only */
	void *pscontext;	/* For path-selector use */
};

/* Callback for hwh_pg_init_fn to use when complete */
void dm_pg_init_complete(struct dm_path *path, unsigned int err_flags);

#endif

Annotation

• Detected declarations: `struct dm_dev`, `struct dm_path`.
• 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.
