Linux continues to innovate in the area of file systems. It supports the largest variety of file systems of any operating system. It also provides cutting-edge file system technology. Two new file systems that are making their way into Linux include the NiLFS(2) log-structured file system and the exofs object-based storage system. Discover the purpose behind these two new file systems and the advantages that they bring.

The only filesystem, which I would consider truly innovative and useful is ZFS. And that has not even made it to Linux yet (various reasons).
I agree that ZFS is both innovative and useful and it would have been great if it were possible to include it in Linux, but as that is not possible there's coming up another fs to use: Btrfs. It seems it has more-or-less all the capabilities of ZFS and a few of its own new ones.
No, it's not the same thing, but it's close 
Unfortunately it's not yet ready for consumption, but hopefully soon.

You do realize ADV-FS did most of those things over 10 years ago...

Filesystems nowadays need the ability to grow or shrink on the fly, hot snapshots, building/moving/expanding or even dissolving RAIDs etc.
And that has to happen while still being online and mounted.
