The general reason why innodb redo log file is limited by 512G is that log_block_convert_lsn_to_no() returns value limited by 1G. But there is no need to have unique log block numbers in log group. The fix removes 512G limit and limits log group size by (uint32_t maximum value) * (minimum page size), which, in turns, can be removed if fil_io() is no longer used for innodb redo log io.
