Linux 7.2 Optimization Shows +5% IOPS For EXT4 & XFS After Moving Around Two Lines Of Code

In addition to the surprising impact of /proc/filesystems read optimizations for Linux 7.2 , another one of the VFS pull requests for this next kernel version is delivering some nice improvements for EXT4 and XFS around IOmap, the framework that maps file data offsets in memory to their physical locations on storage.

Among the IOmap changes now merged for the Linux kernel is an optimization showing nice benefit for EXT4 and XFS when running with NVMe SSD storage and using IO_uring:
"Skip the memset of the iomap

Intel Performance Skills: New Open-Source Project Leveraging AI For Linux Performance Optimizations

The newest open-source project out of Intel is the Intel Performance Skills project that is providing AI agent skills to help with CPU performance analysis and performance optimizations on Linux.

Intel Performance Skills began coming about in recent weeks to provide AI agents with structured, multi-step workflows for profiling, performance anti-patterns in source code, and more. The Intel Performance Skills can work with GitHub CLI / Copilot, Claude COde, OpenAI Codex, Gemini CLI, and OpenCode.

The MIT-licensed project can detect coding patterns

FreeBSD Receives Funding To Launch AI-Assisted Vulnerability Discovery

The FreeBSD Project announced today the launch of an AI-Assisted Vulnerability Discovery Project with grant funding provided by the Linux Foundation backed Alpha-Omega project. Alpha-Mega has sponsors including Microsoft, AWS, Google, Anthrophic, OpenAI, and others who will now be helping with FreeBSD uncovering new vulnerabilities by leveraging AI.

This is anticipated to be a six month project with a goal to reduce the number of exploitable vulnerabilities in the FreeBSD codebase. This is a $250k USD grant for key members of the

GCC Steering Committee Supports Inclusion Of WebAssembly Backend

Last month a new GCC back-end was proposed for WebAssembly to allow C/C++ code to be compiled to WASM with this GNU compiler toolchain. The GCC Steering Committee has evaluated it and approves the notion of WebAssembly back-end for GCC.

Rather than having to rely on LLVM-based tooling for converting code to WebAssembly, a modern GCC back-end was developed. It's still in early stages of development and not yet feature complete, but at least the concept of WASM back-end
