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.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/types.h`, `linux/kernel.h`, `linux/init.h`, `linux/module.h`, `linux/kthread.h`, `linux/err.h`, `linux/spinlock.h`, `linux/smp.h`.
• Detected declarations: `struct rcu_torture_reader_check`, `struct rcu_torture`, `struct rt_read_seg`, `struct rcu_torture_ops`, `struct rcu_torture_one_read_state`, `struct rcu_torture_one_read_state_updown`, `struct fwd_cb_state`, `struct rcu_fwd_cb`, `struct rcu_launder_hist`, `struct rcu_fwd`.
• Atlas domain: Core OS / Scheduler, Processes, Timers, Sync, And Syscalls.
• Implementation status: integration 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.
