These two tests simulate log failure during a reflink operation. However, the contents of the target of the reflink operation depend on the block size, so we cannot hardcode md5 hashes in this test. Since the whole point of the test is to ensure that the the complex chain of transactions actually finishes no matter where the interruption, it is sufficient simply to run the usual end-of-test fsck to look for corrupt metadata.
