Ok, so the issue is that for this particular test configuration, btrfs has a minimum file system size. What about changing _scratch_mkfs_sized so that if MIN_FS_SIZE is set, the file system created will be at least MIN_FS_SIZE in size. This way it sets the minimum file system size for all tests, not just generic/224, and any test configuration, whether it be ext4, xfs, or btrfs where the data and metadata block size are the same, don't have to take extra time -- only the test configuration of btrfs with data_block_size != metadata_block_size.
