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

• linux/cpufeature.h

Detected Declarations

• function arch_raid6_init

Annotated Snippet

#include <linux/cpufeature.h>

extern const struct raid6_calls raid6_s390vx8;
extern const struct raid6_recov_calls raid6_recov_s390xc;

static __always_inline void __init arch_raid6_init(void)
{
	if (cpu_has_vx())
		raid6_algo_add(&raid6_s390vx8);
	else
		raid6_algo_add_default();
	raid6_recov_algo_add(&raid6_recov_s390xc);
}

Annotation

• Immediate include surface: `linux/cpufeature.h`.
• Detected declarations: `function arch_raid6_init`.
• 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.
