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

• stdarg.h

Detected Declarations

• struct perf_error_ops

Annotated Snippet

struct perf_error_ops {
	int (*error)(const char *format, va_list args);
	int (*warning)(const char *format, va_list args);
};

int perf_error__register(struct perf_error_ops *eops);
int perf_error__unregister(struct perf_error_ops *eops);

Annotation

• Immediate include surface: `stdarg.h`.
• Detected declarations: `struct perf_error_ops`.
• 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.
