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 an operation table; this is where Linux turns generic core objects into subsystem-specific behavior.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/spinlock.h
• linux/interrupt.h
• linux/delay.h
• linux/pci.h
• linux/workqueue.h

Detected Declarations

• struct tifm_device_id
• struct tifm_driver
• struct tifm_dev
• struct tifm_driver
• struct tifm_adapter
• function tifm_set_drvdata

Annotation

• Immediate include surface: `linux/spinlock.h`, `linux/interrupt.h`, `linux/delay.h`, `linux/pci.h`, `linux/workqueue.h`.
• Detected declarations: `struct tifm_device_id`, `struct tifm_driver`, `struct tifm_dev`, `struct tifm_driver`, `struct tifm_adapter`, `function tifm_set_drvdata`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: pattern 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.
