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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `crypto/algapi.h`, `crypto/internal/aead.h`, `linux/atomic.h`, `linux/err.h`, `linux/init.h`, `linux/module.h`, `linux/slab.h`, `linux/kobject.h`.
• Detected declarations: `struct pcrypt_instance_ctx`, `struct pcrypt_aead_ctx`, `function pcrypt_aead_setkey`, `function pcrypt_aead_setauthsize`, `function pcrypt_aead_serial`, `function pcrypt_aead_done`, `function pcrypt_aead_enc`, `function pcrypt_aead_encrypt`, `function pcrypt_aead_dec`, `function pcrypt_aead_decrypt`.
• Atlas domain: Kernel Services / crypto.
• Implementation status: integration implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
