RFE: support for FS_IOC_SETFSLABEL
Currently GNOME Disks umounts a file system before it can change its label. And then doesn't mount the file system. Since umount isn't possible sometimes, e.g. sysroot, or any other in-use file system such as /home, the current implementation is limited.
Currently btrfs, f2fs, xfs support this ioctl. I'm not sure if Disks would directly use the ioctl or have udisks do this instead, so I filed a udisks RFE as well.
