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/types.h

Detected Declarations

• struct unwind_stacktrace
• struct unwind_user_frame
• struct unwind_user_state
• enum unwind_user_type_bits
• enum unwind_user_type

Annotated Snippet

	unsigned int	nr;

struct unwind_user_frame {
	s32 cfa_off;
	s32 ra_off;
	s32 fp_off;
	bool use_fp;
};

struct unwind_user_state {
	unsigned long				ip;
	unsigned long				sp;
	unsigned long				fp;
	unsigned int				ws;
	enum unwind_user_type			current_type;
	unsigned int				available_types;

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct unwind_stacktrace`, `struct unwind_user_frame`, `struct unwind_user_state`, `enum unwind_user_type_bits`, `enum unwind_user_type`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
