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 fch_hdr
• struct fcllc

Annotated Snippet

struct fch_hdr {
	__u8  daddr[FC_ALEN];		/* destination address */
	__u8  saddr[FC_ALEN];		/* source address */
};

/* This is a Fibre Channel LLC structure */
struct fcllc {
	__u8  dsap;			/* destination SAP */
	__u8  ssap;			/* source SAP */
	__u8  llc;			/* LLC control field */
	__u8  protid[3];		/* protocol id */
	__be16 ethertype;		/* ether type field */
};

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct fch_hdr`, `struct fcllc`.
• 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.
