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/list.h

Detected Declarations

• struct syscore_ops
• struct syscore

Annotated Snippet

	int (*suspend)(void *data);
	void (*resume)(void *data);
	void (*shutdown)(void *data);
};

	struct list_head node;
	const struct syscore_ops *ops;
	void *data;
};

extern void register_syscore(struct syscore *syscore);
extern void unregister_syscore(struct syscore *syscore);
#ifdef CONFIG_PM_SLEEP
extern int syscore_suspend(void);

#endif
extern void syscore_shutdown(void);

Annotation

• Immediate include surface: `linux/list.h`.
• Detected declarations: `struct syscore_ops`, `struct syscore`.
• 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.
