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.

Annotation

• Immediate include surface: `linux/crc32.h`, `linux/export.h`, `linux/module.h`, `linux/types.h`, `crc32table.h`, `crc32.h`.
• Detected declarations: `function crc32`, `function crc32_be_base`, `function crc32c_base`, `function crc32_optimizations`, `function crc32_le`, `function crc32_be`, `function crc32c`, `function crc32_mod_init`, `function crc32_mod_exit`, `module init crc32_mod_init`.
• Atlas domain: Kernel Services / lib.
• Implementation status: integration 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.
