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 xt_string_info

Annotated Snippet

	char	  algo[XT_STRING_MAX_ALGO_NAME_SIZE];
	char 	  pattern[XT_STRING_MAX_PATTERN_SIZE];
	__u8  patlen;
	union {
		struct {
			__u8  invert;

		struct {
			__u8  flags;

	} u;

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct xt_string_info`.
• 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.
