| # DESCRIPTION: |
| # 'zfs wait' works when waiting for checkpoint discard to complete. |
| # |
| # STRATEGY: |
| # 1. Create a file |
| # 2. Open a file descriptor pointing to that file. |
| # 3. Delete the file. |
| # 4. Start a background process waiting for the delete queue to empty. |
| # 5. Verify that the command doesn't return immediately. |
| # 6. Close the open file descriptor. |
| # 7. Verify that the command returns soon after the descriptor is closed. |
