Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/rbtree.h
• linux/types.h

Detected Declarations

• struct perf_env
• struct phys_entry
• struct mem2node

Annotated Snippet

	struct rb_root		 root;
	struct phys_entry	*entries;
	int			 cnt;
};

int  mem2node__init(struct mem2node *map, struct perf_env *env);
void mem2node__exit(struct mem2node *map);
int  mem2node__node(struct mem2node *map, u64 addr);

Annotation

• Immediate include surface: `linux/rbtree.h`, `linux/types.h`.
• Detected declarations: `struct perf_env`, `struct phys_entry`, `struct mem2node`.
• Atlas domain: Support Tooling And Documentation / tools.
• 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.
