btrfs balance is done "online", that is, on the (writable-)mounted
filesystem, and the kernel does the real work. It's the tools that work
on the unmounted filesystem, btrfs check, btrfs restore, btrfs rescue,
etc, where the userspace code does the real work, and thus where being
current and having all the latests userspace fixes is vital.
If you can't mount writable, you can't balance.
