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/extcon.h

Detected Declarations

• struct extcon_dev
• function extcon_dev_register
• function extcon_dev_unregister
• function devm_extcon_dev_unregister
• function extcon_dev_free
• function devm_extcon_dev_free
• function extcon_set_state_sync

Annotation

• Immediate include surface: `linux/extcon.h`.
• Detected declarations: `struct extcon_dev`, `function extcon_dev_register`, `function extcon_dev_unregister`, `function devm_extcon_dev_unregister`, `function extcon_dev_free`, `function devm_extcon_dev_free`, `function extcon_set_state_sync`, `function extcon_sync`, `function extcon_set_property`, `function extcon_set_property_sync`.
• 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.
