Liu Bo 9ba1f6e44e Btrfs: do not do balance in readonly mode ... In normal cases, we would not be allowed to do balance in RO mode. However, when we're using a seeding device and adding another device to sprout, things will change: $ mkfs.btrfs /dev/sdb7 $ btrfstune -S 1 /dev/sdb7 $ mount /dev/sdb7 /mnt/btrfs -o ro $ btrfs fi bal /mnt/btrfs -----------------------> fail. $ btrfs dev add /dev/sdb8 /mnt/btrfs $ btrfs fi bal /mnt/btrfs -----------------------> works! It should not be designed as an exception, and we'd better add another check for mnt flags.
