| # FS QA Test No. 240 |
| # |
| # Test that non-block-aligned aio+dio into holes does not leave |
| # zero'd out portions of the file |
| # |
| # QEMU IO to a file-backed device with misaligned partitions |
| # can send this sort of IO |
| # |
| # This test need only be run in the case where the logical block size |
| # of the device can be smaller than the file system block size. |
