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.

Indeed :-) I've actually been surprised, given those complaints about ZFS, that there hasn't been more (and vocal!) opposition to the Btrfs merge.
That said, maybe the kernel architecture of the two does differ somewhat. I had the impression that the ZFS architecture in Solaris included scope for other filesystems (e.g. UFS) to be implemented effectively as plugins to ZFS. Btrfs certainly doesn't seem to include anything like that, although I'm not entirely clear to what extent ZFS *does* vs *could*.
