| # FS QA Test No. 210 |
| # |
| # During reflink, XFS should carry the cowextsz setting to the destination file |
| # if the destination file size is less than the size of the source file, the |
| # length is the size of the source file, both offsets are zero, and the |
| # destination does not already have a cowextsz setting. It should not do so |
| # otherwise. |
