| # |
| # DESCRIPTION: |
| # Take a checkpoint and discard checkpointed data twice. The |
| # idea is to ensure that the background discard zfs thread is |
| # always running and works as expected. |
| # |
| # STRATEGY: |
| # 1. Create pool |
| # 2. Populate it and then take a checkpoint |
| # 3. Do some changes afterwards, and then discard checkpoint |
| # 4. Repeat steps 2 and 3 |
| # |
