Qu Wenruo dc4bbc37a1 btrfs-progs: convert-tests: Add test case for backup superblock migration ... New convert introduced simpler chunk/extent allocation algorithm, at the cost of complex backup superblock migration codes. Use specially built ext2 images to test if btrfs-convert can convert and rollback images without problem. All these special ext2 image have blocks/holes across 2nd btrfs backup superblock. The naming of test image is like the following: |<------superblock migration range----->| 64M 64M + 64K |-Data--|-Data--|/Hole//|-Data--|/Hole//|-Data--|--Data--| = drdhdhdrd These test cases should check all typical layouts and make sure new convert works.
