    Btrfs: fix wrong disk size when writing super blocks · 935e5cc9
    Miao Xie 提交于
    total_size will be changed when resizing a device, and disk_total_size
    will be changed if resizing is successful. Meanwhile, the on-disk super
    blocks of the previous transaction might not be updated. Considering
    the consistency of the metadata in the previous transaction, We should
    use the size in the previous transaction to check if the super block is
    beyond the boundary of the device. Fix it.
