| # FS QA Test 468 |
| # |
| # This testcase is a fallocate variant of generic/392, it expands to test |
| # block preallocation functionality of fallocate. |
| # In this case, we are trying to execute: |
| # 1. fallocate {,-k} |
| # 2. f{data,}sync |
| # 3. power-cuts |
| # 4. recovery filesystem during mount |
| # 5. check inode's metadata |
| # |
| # In the case of fsync, filesystem should recover all the inode metadata, while |
| # recovering i_blocks and i_size at least for fdatasync, so this testcase excepts |
| # that inode metadata will be unchanged after recovery. |
