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/seg6.h

Detected Declarations

• struct seg6_iptunnel_encap

Annotated Snippet

struct seg6_iptunnel_encap {
	int mode;
	struct ipv6_sr_hdr srh[];
};

#define SEG6_IPTUN_ENCAP_SIZE(x) ((sizeof(*x)) + (((x)->srh->hdrlen + 1) << 3))

enum {
	SEG6_IPTUN_MODE_INLINE,
	SEG6_IPTUN_MODE_ENCAP,
	SEG6_IPTUN_MODE_L2ENCAP,
	SEG6_IPTUN_MODE_ENCAP_RED,
	SEG6_IPTUN_MODE_L2ENCAP_RED,

Annotation

• Immediate include surface: `linux/seg6.h`.
• Detected declarations: `struct seg6_iptunnel_encap`.
• 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.
