The article reviews the most significant Linux kernel developments in 2025, including increased Rust integration, community decisions on file systems like Bcachefs and Btrfs, hardware support updates, and Linus Torvalds' commentary on kernel policies and architecture proposals, highlighting ongoing innovation and challenges in kernel development.
The multi-grain timestamps feature, which was intended to address issues with coarse-grained timestamps in the Linux kernel, has been removed after a few weeks due to problems it exposed. The feature was meant to provide more robust timestamp updates for creation/modification times, particularly for file systems like NFS. However, the feature caused subtle bugs and performance impacts, leading to its removal from the kernel. The developers will explore alternative solutions that involve exposing fine-grained timestamps only internally to NFS and not to userspace.
