| # DESCRIPTION: |
| # -w flag for 'zpool trim' waits for trimming to complete for all and only those |
| # vdevs kicked off by that invocation. |
| # |
| # STRATEGY: |
| # 1. Create a pool with 3 vdevs. |
| # 2. Start trimming vdevs 1 and 2 with one invocation of 'zpool trim -w' |
| # 3. Start trimming vdev 3 with a second invocation of 'zpool trim -w' |
| # 4. Cancel the trim of vdev 1. Check that neither waiting process exits. |
| # 5. Cancel the trim of vdev 3. Check that only the second waiting process |
| # exits. |
| # 6. Cancel the trim of vdev 2. Check that the first waiting process exits. |
