Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/module.h
• linux/types.h

Detected Declarations

• struct gcov_info
• struct gcov_link
• enum gcov_action

Annotated Snippet

struct gcov_link {
	enum {
		OBJ_TREE,
		SRC_TREE,
	} dir;
	const char *ext;
};
extern const struct gcov_link gcov_link[];

extern int gcov_events_enabled;
extern struct mutex gcov_lock;

Annotation

• Immediate include surface: `linux/module.h`, `linux/types.h`.
• Detected declarations: `struct gcov_info`, `struct gcov_link`, `enum gcov_action`.
• Atlas domain: Core OS / Scheduler, Processes, Timers, Sync, And Syscalls.
• 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.
