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/mtd/mtd.h
• linux/mtd/partitions.h

Detected Declarations

• struct map_info
• struct platform_device
• struct physmap_flash_data

Annotated Snippet

struct physmap_flash_data {
	unsigned int		width;
	int			(*init)(struct platform_device *);
	void			(*exit)(struct platform_device *);
	void			(*set_vpp)(struct platform_device *, int);
	unsigned int		nr_parts;
	unsigned int		pfow_base;
	char                    *probe_type;
	struct mtd_partition	*parts;
	const char * const	*part_probe_types;
};

Annotation

• Immediate include surface: `linux/mtd/mtd.h`, `linux/mtd/partitions.h`.
• Detected declarations: `struct map_info`, `struct platform_device`, `struct physmap_flash_data`.
• 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.
