Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/compiler.h

Detected Declarations

• struct clk
• struct device
• struct ata_port_info
• struct ahci_host_priv
• struct platform_device
• struct scsi_host_template

Annotation

• Immediate include surface: `linux/compiler.h`.
• Detected declarations: `struct clk`, `struct device`, `struct ata_port_info`, `struct ahci_host_priv`, `struct platform_device`, `struct scsi_host_template`.
• Atlas domain: Core OS / Core Kernel Interface.
• 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.
