source implementation candidate

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/refcount.h
• sys/types.h
• unistd.h

Detected Declarations

• struct thread_map_data
• struct perf_thread_map

Annotated Snippet

struct thread_map_data {
	pid_t	 pid;
	char	*comm;
};

struct perf_thread_map {
	refcount_t	refcnt;
	int		nr;
	int		err_thread;
	struct thread_map_data map[];
};

struct perf_thread_map *perf_thread_map__realloc(struct perf_thread_map *map, int nr);

Annotation

• Immediate include surface: `linux/refcount.h`, `sys/types.h`, `unistd.h`.
• Detected declarations: `struct thread_map_data`, `struct perf_thread_map`.
• 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.
