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/list.h
• linux/types.h
• stdbool.h

Detected Declarations

• struct comm_str
• struct comm

Annotated Snippet

	struct comm_str *comm_str;
	u64 start;
	struct list_head list;
	bool exec;
	union { /* Tool specific area */
		void	*priv;
		u64	db_id;
	};
};

void comm__free(struct comm *comm);
struct comm *comm__new(const char *str, u64 timestamp, bool exec);
const char *comm__str(const struct comm *comm);
int comm__override(struct comm *comm, const char *str, u64 timestamp,
		   bool exec);

Annotation

• Immediate include surface: `linux/list.h`, `linux/types.h`, `stdbool.h`.
• Detected declarations: `struct comm_str`, `struct comm`.
• 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.
