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/errno.h
• linux/types.h
• linux/suspend.h

Detected Declarations

• struct regulator_coupler
• struct regulator_dev
• struct regulator_coupler
• function regulator_coupler_register
• function regulator_check_consumers
• function regulator_check_voltage
• function regulator_get_voltage_rdev
• function regulator_set_voltage_rdev
• function regulator_do_balance_voltage

Annotation

• Immediate include surface: `linux/errno.h`, `linux/types.h`, `linux/suspend.h`.
• Detected declarations: `struct regulator_coupler`, `struct regulator_dev`, `struct regulator_coupler`, `function regulator_coupler_register`, `function regulator_check_consumers`, `function regulator_check_voltage`, `function regulator_get_voltage_rdev`, `function regulator_set_voltage_rdev`, `function regulator_do_balance_voltage`.
• 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.
