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/sched.h
• uapi/linux/kcov.h

Detected Declarations

• struct task_struct
• enum kcov_mode
• function kcov_remote_start_common
• function kcov_remote_start_usb
• function kcov_remote_start_usb_softirq
• function kcov_remote_stop_softirq
• function kcov_task_init
• function kcov_remote_start_common

Annotation

• Immediate include surface: `linux/sched.h`, `uapi/linux/kcov.h`.
• Detected declarations: `struct task_struct`, `enum kcov_mode`, `function kcov_remote_start_common`, `function kcov_remote_start_usb`, `function kcov_remote_start_usb_softirq`, `function kcov_remote_stop_softirq`, `function kcov_task_init`, `function kcov_remote_start_common`.
• 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.
