Why This File Exists

Shared kernel service surface used by multiple subsystems, including helpers, cryptography, virtualization support, and async I/O infrastructure.

• Shared kernel service surface used by multiple subsystems, including helpers, cryptography, virtualization support, and async I/O infrastructure.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

if (fb != nn) {
			for (j = 1; j < nroots; j++) {
				par[j] ^= alpha_to[rs_modnn(rs, fb +
							 genpoly[nroots - j])];
			}
		}
		/* Shift */
		memmove(&par[0], &par[1], sizeof(uint16_t) * (nroots - 1));
		if (fb != nn) {
			par[nroots - 1] = alpha_to[rs_modnn(rs,
							    fb + genpoly[0])];
		} else {
			par[nroots - 1] = 0;
		}
	}
	return 0;
}

Annotation

• Atlas domain: Kernel Services / lib.
• 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.
