ConfigFS is seeing a new maintainer step up to manage this RAM-based file-system. With Andreas Hindborg taking over maintainership of ConfigFS he's also landing patches authored by him for adding Rust programming language support to this file-system.

ConfigFS is a RAM-based file-system for a converse of sysfs functionality for user-space driven kernel object configuration. ConfigFS makes it easy to expose kernel data structures for different purposes. With Linux 6.16 there is now going to be a Rust API to ConfigFS for having a memory-safe API for interacting with it. As part of the Rust integration is also adding a sample Rust program for demonstrating the ConfigFS + Rust interface.

The ConfigFS code for Linux 6.16 also now allows creating read-write files with custom permissions to better protect secrets written through ConfigFS.
