Why This File Exists

Rust-side wrappers and abstractions around kernel C APIs, ownership contracts, allocation, synchronization, and module integration.

• Rust-side wrappers and abstractions around kernel C APIs, ownership contracts, allocation, synchronization, and module integration.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/cred.h

Detected Declarations

• function rust_helper_put_cred

Annotated Snippet

#include <linux/cred.h>

__rust_helper const struct cred *rust_helper_get_cred(const struct cred *cred)
{
	return get_cred(cred);
}

__rust_helper void rust_helper_put_cred(const struct cred *cred)
{
	put_cred(cred);
}

Annotation

• Immediate include surface: `linux/cred.h`.
• Detected declarations: `function rust_helper_put_cred`.
• Atlas domain: Rust Kernel Layer / Rust API Membrane.
• 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.
