Module filesystem 

Filesystem-level operations: metadata, sync, label, and resize

Operations that apply to a btrfs filesystem as a whole rather than to any individual device or subvolume: querying filesystem info (UUID, device count, node size), syncing pending writes to disk, reading/writing the human-readable label, and resizing a device within the filesystem.
