Just trivial changes: - Add a SPDX header; - Add it to filesystems/index.rst. While here, adjust document title, just to make it use the same style of the other docs.

features while focusing on fault tolerance, repair and easy administration.

* Extent based file storage (2^64 max file size)
|
|
* Space efficient packing of small files
|
|
* Space efficient indexed directories
|
|
* Dynamic inode allocation
|
|
* Writable snapshots
|
|
* Subvolumes (separate internal filesystem roots)
|
|
* Object level mirroring and striping
|
|
* Checksums on data and metadata (multiple algorithms available)
|
|
* Compression
|
|
* Integrated multiple device support, with several raid algorithms
|
|
* Offline filesystem check
|
