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 ebt_mac_wormhash_tuple
• struct ebt_mac_wormhash
• struct ebt_among_info

Annotated Snippet

	__u32 cmp[2];
	__be32 ip;
};

	int table[257];
	int poolsize;
	struct ebt_mac_wormhash_tuple pool[];
};

#define ebt_mac_wormhash_size(x) ((x) ? sizeof(struct ebt_mac_wormhash) \
		+ (x)->poolsize * sizeof(struct ebt_mac_wormhash_tuple) : 0)

struct ebt_among_info {
	int wh_dst_ofs;
	int wh_src_ofs;
	int bitmask;
};

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct ebt_mac_wormhash_tuple`, `struct ebt_mac_wormhash`, `struct ebt_among_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.
