Subject: [PATCH 16/28] 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
|
|

this, but here it is just in case.
