Linux Kernel 6.16: Subtle Changes, Significant Improvements

The Linux 6.16 kernel release, while seemingly minor, packs significant improvements. Rust integration deepens with new bindings for the driver core and PCI subsystem, simplifying the addition of Rust-based hardware drivers. The Direct Rendering Manager (DRM) gains new Rust abstractions, boosting graphics performance and reducing vulnerabilities. XFS and Ext4 filesystems receive enhancements resulting in performance boosts up to 37%. Security is enhanced with support for Intel TXT and TDX, and improvements are made for Intel APX and Nvidia Blackwell GPUs. Network performance is also boosted with changes to how TCP/IP interacts with DMABUF.
