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.

EXT4?

I hope this question isn't out of place here: Was the EXT4 corruption bug ever definitely fixed, and if so, in what version?

Which one? I have never heard of one. There was one in btrfs, right, and btrs doesn't have a fsck, which makes corruption to its metadata much worse, but ext4 has been remarkably stable and reliable.

Regarding BTRFS, it still is surprisingly unstable, like e.g. just recently I tried to copy a few files from my N900 to my server running BTRFS and it resulted in the BTRFS - kernel module crashing every single time and me having to reboot the system to get it useable again. Such an odd bug, but I seem to keep hitting bugs with BTRFS all the time and I'm starting to wonder if I should just switch to something else.

The bug was fixed in late October, so I would assume releases since then are patched.

Yes, the October corruption thing (http://lwn.net/Articles/521022/) is gone.

Actually, an interesting read is how people, were too panicky about it: http://lwn.net/Articles/521803/

Yeah, this was the one I was referring too. Thanks, and glad to see it's fixed.
