# Specially created e2image dump to test backup superblock migration for
# new convert.
# These images will cause the following problems if convert doesn't handle
# backup superblock migration well:
# 1) Assert while building free space tree
# 2) Error copying inodes
# 3) Discontinuous file extents after convert
# 4) Overlap file extents
# 5) Unable to rollback
