| # |
| # Ensure that we can reflink the last block of a file whose size isn't |
| # block-aligned. |
| # - Create two 'a' files file whose size isn't block-aligned. |
| # - Create two 'b' files file whose size isn't block-aligned. |
| # - Reflink the last block of file1 to the last block in file2 and file3. |
| # - Check that files 1-2 match, 3-4 don't match, and that nothing matches 3. |
| # - Check that the ends of 1-3 match, and 1-3 do not match the end of file4. |
