    30   1. `BLOCK_DEVICE_NOOP` : No operation
    31   1. `BLOCK_DEVICE_READ` : Transfer from flock device to memory
    32   1. `BLOCK_DEVICE_WRITE` : Transfer from memory to block device
     30   * `BLOCK_DEVICE_NOOP` : No operation
     31   * `BLOCK_DEVICE_READ` : Transfer from flock device to memory
     32   * `BLOCK_DEVICE_WRITE` : Transfer from memory to block device

    39   1. `BLOCK_DEVICE_WRITE_SUCCESS`
    40   1. `BLOCK_DEVICE_READ_ERROR`
    41   1. `BLOCK_DEVICE_WRITE_ERROR`
    42   1. `BLOCK_DEVICE_ERROR`
     36   * `BLOCK_DEVICE_IDLE`
     37   * `BLOCK_DEVICE_BUSY`
     38   * `BLOCK_DEVICE_READ_SUCCESS`
     39   * `BLOCK_DEVICE_WRITE_SUCCESS`
     40   * `BLOCK_DEVICE_READ_ERROR`
     41   * `BLOCK_DEVICE_WRITE_ERROR`
