The redo log format will be changed by MDEV-12288, and it could be changed further during MariaDB 10.3 development. We will allow startup from a clean redo log from any earlier InnoDB version (up to MySQL 5.7 or MariaDB 10.3), but we will refuse to do crash recovery from older-format redo logs. recv_log_format_0_recover(): Remove a reference to MySQL documentation, which may be misleading when it comes to MariaDB. recv_log_recover_10_2(): Check if a MariaDB 10.2.2/MySQL 5.7.9 redo log is clean. recv_find_max_checkpoint(): Invoke recv_log_recover_10_2() if the redo log is in the MariaDB 10.2.2 or MySQL 5.7.9 format.
