Hi all, this patch adds the command "btrfs filesystem label" to change (or show) the label of a filesystem. This patch is a subset of the one written previously by Morey Roof. I included the user space part only. So it is possible only to change/show a label of a *single device* and *unounted* filesystem. The reason of excluding the kernel space part, is to simplify the patch in order to speed the check and then the merging of the patch itself. In fact I have to point out that in the past there was almost three attempts to propose this patch, without success neither complaints. Chris, let me know how you want to proceed. I know that you are very busy, and you prefer to work to stabilize btrfs instead adding new feature. But I think that changing a label is a *essential* feature for a filesystem managing tool. Think about a mount by LABEL. To show a label $ btrfs filesystem label <device> To set a label $ btrfs filesystem label <device> <newlabel> Please guys, give a look to the source. Comments are welcome. You can pull the source from the branch "label" of the repository http://cassiopea.homelinux.net/git/btrfs-progs-unstable.git Regards G.Baroncelli Signed-off-by: Chris Mason <chris.mason@oracle.com>
