Support for the 'ceph' filesystem

Ceph is a cool distributed filesystem which is now in the mainline kernel (experimental)

Whats especially cool about it is not only are there native kernel drivers, but it also has libraries to applications can access it directly. There is even a kvm driver for it, as storage without going through the host kernel. There is also an S3 compatible interface if you are in to that sort of thing.

Ceph is also outstanding because it doesnt have any sort of sailing companies involved (Oracle for example)
