You may want to merge this one into the existing overflow tests, check convert-tests/018-fs-size-overflow, which is doing the 64g overflow test already. Otherwise it looks good.

This test cases will test whether btrfs-convert can handle ext4 filesystems that are largerthan 16TiB. At 16TiB block numbers overflow 32 bits, btrfs-convert either fails or corrupts fs if 64 bit block numbers are not supported.
