Linux 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 to replace quickly a disk, a new filesystem F2FS optimized for SSDs, support of 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.

RE[3]: EXT4?

Member since:

Ted Tso, creator of EXT4 explains that lot of Linux filesystems are unsafe, because of the hunt for performance instead of stabilty

"In the case of reiserfs, Chris Mason submitted a patch 4 years ago to turn on barriers by default, but Hans Reiser vetoed it. Apparently, to Hans, winning the benchmark demolition derby was more important than his user's data. (It's a sad fact that sometimes the desire to win benchmark competition will cause developers to cheat, sometimes at the expense of their users.)...We tried to get the default changed in ext3, but it was overruled by Andrew Morton, on the grounds that it would represent a big performance loss, and he didn't think the corruption happened all that often (!!!!!) --- despite the fact that Chris Mason had developed a python program that would reliably corrupt an ext3 file system if you ran it and then pulled the power plug "
