  The 2024 Linux Storage, Filesystem, Memory-Management, and BPF Summit included a tense session on the use of Rust code in the kernel's filesystem layer. The Rust topic returned in 2025 in a session run by Andreas Hindborg, with a scope that also covered the storage and memory-management layers. A lot of progress has been made, and the discussion was less adversarial this year, but...

  The famfs filesystem is meant to provide a shared-memory filesystem for large data sets that are accessed for computations by multiple systems. It was developed by John Groves, who led a combined filesystem and memory-management session at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF) to discuss it. The session was a follow-up to the famfs session at last year's summit,...

  [$] Improving FUSE writeback performance

  In a combined filesystem and memory-management session at the 2025 Linux Storage, Filesystem, Memory Management, and BPF Summit (LSFMM+BPF), Joanne Koong led a discussion on improving the writeback performance for the Filesystem in Userspace (FUSE) layer. Writeback is how data that is written to the filesystem is actually flushed to the disk; it is the process of writing dirty pages from the page cache...

  Andrew Morton, the lead maintainer for the kernel's memory-management subsystem, tends to be quiet during the Linux Storage, Filesystem, Memory-Management, and BPF Summit, preferring to let the developers work things out on their own. That changes, though, when he leads the traditional development-process session in the memory-management track. At the 2025 gathering, this discussion covered a number of ways in which the process could...
