Versin 0.17 of the Linux filesystem btrfs has been released. The main news on this release is that it has been included in the Linus' tree. The changes include support of transparent compression, seed devices, improved block sharing while moving extents, improved block allocation and many bug fixes and performance improvements. Also, the disk format is not expected to change unless a critical bug is found.

In my opinion, Btrfs will be no match for ZFS. ZFS has removed the unnecessary layering, which helped to simplyfy the code and resulted in fewer lines of code and better integration between the "layers". Btrfs will be just filesystem, whereas ZFS is a volume manager and RAID too. This allows for very nice features, like self healing in situation, when only one side of mirror gets corrupt (in case of hw failure for example). Since Btrfs will use existing RAID implementation (AFAIK) it won't be able to do that. But this is just one example which comes to my mind ATM.
