Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/auxiliary_bus.h
• linux/compiler_types.h
• linux/container_of.h

Detected Declarations

• struct regmap
• struct spinlock_t
• struct ep93xx_regmap_adev
• enum ep93xx_soc_model

Annotated Snippet

	void (*write)(struct regmap *map, spinlock_t *lock, unsigned int reg,
		      unsigned int val);
	void (*update_bits)(struct regmap *map, spinlock_t *lock,
			    unsigned int reg, unsigned int mask, unsigned int val);
};

Annotation

• Immediate include surface: `linux/auxiliary_bus.h`, `linux/compiler_types.h`, `linux/container_of.h`.
• Detected declarations: `struct regmap`, `struct spinlock_t`, `struct ep93xx_regmap_adev`, `enum ep93xx_soc_model`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
