Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.
• Exports symbols or registers init work; inspect boot/module ordering and who consumes the exported contract.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Annotation

• Immediate include surface: `linux/init.h`, `linux/kernel.h`, `linux/module.h`, `linux/slab.h`, `linux/configfs.h`.
• Detected declarations: `struct childless`, `struct simple_child`, `struct simple_children`, `function childless_showme_show`, `function childless_storeme_show`, `function childless_storeme_store`, `function childless_description_show`, `function simple_child_storeme_show`, `function simple_child_storeme_store`, `function simple_child_release`.
• Atlas domain: Support Tooling And Documentation / samples.
• Implementation status: integration 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.
