BTRFS_FS

Btrfs filesystem (EXPERIMENTAL) Unstable disk format

Btrfs is a new filesystem with extents, writable snapshotting,
support for multiple devices and many more features.

Btrfs is highly experimental, and THE DISK FORMAT IS NOT YET
FINALIZED.  You should say N here unless you are interested in

To compile this file system support as a module, choose M here. The
module will be called btrfs.

If unsure, say N.
