make "btrfs filesystem label" command actually work
This simple patch makes "btrfs filesystem label" command actually work. On tmp branch, commit d1dc6a9, "btrfs filesystem label" functionality was introduced. However the commit lacks one component that lets "btrfs" accept "filesystem label" command. Test case: /dev/loop0 WARNING! - Btrfs Btrfs v0.19 IS EXPERIMENTAL WARNING! - see http://btrfs.wiki.kernel.org before using fs created label old on /dev/loop0 nodesize 4096 leafsize 4096 sectorsize 4096 size 1.00GB Btrfs Btrfs v0.19 old new FATAL: the filesystem has to be unmounted new Not sure if you need if you need a signoff for something as trivial as this, but here it is just in case.
