btrfs: test newly supported cases of cloning inline extents
Test several scenarios of cloning operations where the source range includes inline extents. They used to not be supported on btrfs because their implementation was not straightforward, and therefore these operations used to fail with errno EOPNOTSUPP on older kernels. This currently fails on any released kernel. It passes only when the patch with the following subject is applied: "Btrfs: implement full reflink support for inline extents" Signed-off-by: Filipe Manana <fdmanana@suse.com> Reviewed-by: Josef Bacik <josef@toxicpanda.com> Signed-off-by: Eryu Guan <guaneryu@gmail.com>
