For 64k block size, With 256MiB as the XFS filesystem size and 168 MiB as the size of the clone source file, we end up hitting ENOSPC when cloning the source file. This happens due to lack of space for housing the corresponding metadata. This scenario also occurs when using a 512MiB XFS filesystem and 300MiB clone source file. Hence this commit increases the size of the test filesystem to 1 GiB and the size of the clone source file to 768MiB.
