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.
