Now xfs_copy already full support to copy a V5 XFS. But for above old problem, xfstests use below patch to make sure xfs_copy always use "-d" option to copy a V5 XFS: 8346e53 common: append -d option to XFS_COPY_PROG when testing v5 xfs That cause xfstests miss the coverage of copying a V5 XFS without "-d". For test this feature I did below things: 1. Changed init_rc(), add "-d" to $XFS_COPY_PROG if xfs_copy can't copy a V5 XFS properly. 2. xfs/073 test V4 xfs forcibly by specify "-m crc=0" in case. I think it's useless now, so remove it. 3. Changed xfs/032. If xfs_copy full support to copy a V5 XFS, test with and without "-d" option, or only test with "-d" option. Signed-off-by: Zorro Lang --- Hi, V2: 1. remove require_xfs_copy() function 2. change the code logic of init_rc function about how to add "-d" to $XFS_COPY_PROG 3. remove xfs_copy "-d" option of xfs/032 V3: add comments to explain the change in init_rc() V4: Due to xfs/032 test "xfs_copy -d" by default, I don't want to change the original test coverage. So if xfs_copy full support to copy a V5 XFS, then test with and without "-d" option twice.
