[$] Policies for merging new filesystems
In a filesystem-track session at the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Amir Goldstein wanted to discuss his proposed documentation on adding new filesystems to the kernel. There are a number of unmaintained and untestable filesystems already in the kernel, which are a burden to VFS-layer developers who are trying to make sweeping changes, such as switching to folios and the "new" mount API. Goldstein's document is an attempt to head off the addition of filesystems that may increase that burden down the road.
IBM's "Project Lightwell"
IBM has sent out a press release touting a claimed $5 billion investment into an operation called Project Lightwell: Project Lightwell will establish a trusted enterprise clearinghouse combined with a global force of engineers to identify and fix vulnerabilities at scale. The clearinghouse will serve as a security coordination layer, using advanced AI capabilities to validate and test fixes across an unprecedented volume of open source code. These capabilities will be offered through commercial subscriptions, allowing enterprises to integrate secure patches directly into their existing software supply chains with enterprise-grade validation and lifecycle management. Toward the bottom, it does also mention sharing vulnerability information with upstream projects.
[$] Separating memory descriptors from struct page
The kernel's memory-management subsystem is currently partway through a multi-year project to replace the page structure (which represents a page of physical memory) with memory descriptors. At the 2026 Linux Storage, Filesystem, Memory Management, and BPF Summit, Vishal Moola ran a fast-paced session in the memory-management track to describe the current state of that work and what is likely to happen next.

Intel Arc Pro B70 BMG-G31 Linux Gaming Performance
In recent weeks we have been exploring different areas of the Intel Arc Pro B70 graphics performance on Linux from various OpenCL and Vulkan to Level Zero compute benchmarks, scaling up to four Arc Pro B70 graphics cards, comparing to NVIDIA RTX PRO Blackwell, and other relevant tests. While not intended for gaming, many Phoronix readers keep raising requests for seeing the Arc Pro B70 performance for Linux gaming given the lack of any consumer BMG-G31 GPU. So for those curious, here is a look at the Linux gaming performance with the Arc Pro B70 graphics card.
