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:
#===
This patch comes from one of project ideas on btrfs's wiki:
Quote:
Given a block number on a disk, the Btrfs metadata can find all the files and
directories that use or care about that block. Some utilities to walk these
back refs and print the results would help debug corruptions.

When building from tmp branch I got this error:
mkfs.c: In function ‘main’:

Over the last few weeks, I've been playing with a foolish idea,
mostly triggered by a cluster of people being confused by btrfs's free
space reporting (df vs btrfs fi df vs btrfs fi show). I also wanted an
excuse, and some code, to mess around in the depths of the FS data
structures.

Hi all,
I have been using btrfs as my / partition on my fedora 14 box for a
while now and until yesterday it was working a treat.
Had an unexpected power fail during the night and now my os crashes when
mounting /
Most of my data is backed up, but there is some data which I don't want
to lose on
