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.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/task_work.h
• linux/unwind_user.h
• linux/unwind_deferred_types.h

Detected Declarations

• function unwind_reset_info
• function unwind_task_init
• function unwind_deferred_init
• function unwind_deferred_request
• function unwind_deferred_cancel

Annotation

• Immediate include surface: `linux/task_work.h`, `linux/unwind_user.h`, `linux/unwind_deferred_types.h`.
• Detected declarations: `function unwind_reset_info`, `function unwind_task_init`, `function unwind_deferred_init`, `function unwind_deferred_request`, `function unwind_deferred_cancel`.
• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: source 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.
