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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/module.h
• linux/kernel.h
• linux/debugfs.h
• linux/fpu.h
• test_fpu.h

Detected Declarations

• function kernel_fpu_begin
• function test_fpu_init
• function test_fpu_exit
• module init test_fpu_init

Annotated Snippet

module_init(test_fpu_init);
module_exit(test_fpu_exit);

Annotation

• Immediate include surface: `linux/module.h`, `linux/kernel.h`, `linux/debugfs.h`, `linux/fpu.h`, `test_fpu.h`.
• Detected declarations: `function kernel_fpu_begin`, `function test_fpu_init`, `function test_fpu_exit`, `module init test_fpu_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.
