diegocg writes "Linux kernel 3.8 has been released. This release includes support in Ext4 for embedding very small files in the inode, which greatly improves the performance for these files and saves some disk space. There is also a new Btrfs feature that allows for quick disk replacement, a new filesystem F2FS optimized for SSDs; support for filesystem mount, UTS, IPC, PID, and network namespaces for unprivileged users; accounting of kernel memory in the memory resource controller; journal checksums in XFS; an improved NUMA policy redesign; and, of course, the removal of support for 386 processors. Many small features and new drivers and fixes are also available. Here's the full list of changes."
