Annotated Snippet

What:		/sys/devices/.../resource_in_use
Date:		January 2013
Contact:	Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Description:
		The /sys/devices/.../resource_in_use attribute is only present
		for device objects representing ACPI power resources.

		If present, it contains a number (0 or 1) representing the
		current status of the given power resource (0 means that the
		resource is not in use and therefore it has been turned off).

		This attribute is read-only.

Annotation

• Atlas domain: Support Tooling And Documentation / Documentation.
• Implementation status: atlas-only.

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.
