Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct arc4_ctx

Annotated Snippet

struct arc4_ctx {
	u32 S[256];
	u32 x, y;
};

int arc4_setkey(struct arc4_ctx *ctx, const u8 *in_key, unsigned int key_len);
void arc4_crypt(struct arc4_ctx *ctx, u8 *out, const u8 *in, unsigned int len);

#endif /* _CRYPTO_ARC4_H */

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct arc4_ctx`.
• Atlas domain: Repository Root And Misc / include.
• 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.
