Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

# Rust null block device driver configuration

	tristate "Rust null block driver (Experimental)"
	depends on RUST && CONFIGFS_FS
	help
	  This is the Rust implementation of the null block driver. Like
	  the C version, the driver allows the user to create virutal block
	  devices that can be configured via various configuration options.

	  If unsure, say N.

Annotation

• Atlas domain: Driver Families / drivers/block.
• 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.
