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/sched.h
• linux/rcupdate.h
• linux/cleanup.h

Annotation

• Immediate include surface: `linux/sched.h`, `linux/rcupdate.h`, `linux/cleanup.h`.
• Detected declarations: `function rcu_read_lock_trace_held`, `function rcu_read_lock_trace_held`, `function synchronize_rcu_tasks_trace`, `function rcu_read_lock_tasks_trace`, `function synchronize_rcu_tasks_trace`, `function rcu_read_lock_trace`, `function call_rcu_tasks_trace`, `function rcu_read_lock_trace`, `function rcu_barrier_tasks_trace`, `function rcu_tasks_trace_expedite_current`.
• 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.
