Rust for Linux proposes an Ownable adapter for C-allocated objects

lwn.net by daroc Editor score 7/10

The proposed Ownable trait lets Rust code manage the cleanup responsibility for objects allocated in C, without requiring Rust to deallocate them. It illustrates the ownership boundaries needed to integrate memory-safe code into an existing kernel.

What

- Rust for Linux proposed an Ownable trait adapter for objects allocated in C and cleaned up by Rust.

How

- The adapter models Rust responsibility for cleanup without requiring Rust to deallocate the C-allocated object.

Why it matters

- It aims to bridge Rust ownership semantics with existing C kernel code.
