| # DESCRIPTION: |
| # With 'compression' set, a file with non-power-of-2 blocksize storage space |
| # can be freed as will normally. |
| # |
| # STRATEGY: |
| # 1. Set 'compression' or 'compress' to on or lzjb |
| # 2. Set different recordsize with ZFS filesystem |
| # 3. Repeatedly using 'randfree_file' to create a file and then free its |
| # storage space with different range, the system should work normally. |
| # |
