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

• stddef.h
• linux/types.h

Detected Declarations

• struct parse_tag

Annotated Snippet

struct parse_tag {
	char tag;
	int  mult;
};

unsigned long parse_tag_value(const char *str, struct parse_tag *tags);

double convert_unit_double(double value, char *unit);
unsigned long convert_unit(unsigned long value, char *unit);
int unit_number__scnprintf(char *buf, size_t size, u64 n);

Annotation

• Immediate include surface: `stddef.h`, `linux/types.h`.
• Detected declarations: `struct parse_tag`.
• 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.
