Add the "btrfs filesystem label" command 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.
