The test case passes file offsets which are aligned to 4k block size. This causes btrfs_ioctl_clone() to return with -EINVAL for larger block sizes. Fix this by computing file offsets at run time based on the block size of the underlying filesystem. Signed-off-by: Chandan Rajendra <chandan@linux.vnet.ibm.com> --- There are some more test cases which assume 4k as the underlying filesystem's block size. I am planning to fix them using the final solution agreed upon by the community. common/filter | 37 ++++ tests/btrfs/052 | 125 +++++++----- tests/btrfs/052.out | 546 +++++++++++++++++++++++----------------------------- 3 files changed, 358 insertions(+), 350 deletions(-)
