| # Description: |
| # zdb -c will display the same checksum as -ddddddbbbbbb |
| # |
| # Strategy: |
| # 1. Create a pool |
| # 2. Write some data to a file |
| # 3. Run zdb -ddddddbbbbbb against the file |
| # 4. Record the checksum and DVA of L0 block 0 |
| # 5. Run zdb -R with :c flag and match the checksum |
| |
