If InnoDB crash recovery was needed, the InnoDB function srv_start() would invoke extra validation, reading something from every InnoDB data file. This should be unnecessary now that MDEV-14717 made RENAME operations crash-safe inside InnoDB (which can be disabled in MariaDB 10.2 by setting innodb_safe_truncate=OFF). dict_check_sys_tables(): Skip tables that would be dropped by row_mysql_drop_garbage_tables(). Perform extra validation only if innodb_safe_truncate=OFF, innodb_force_recovery=0 and crash recovery was needed. dict_load_table_one(): Validate the root page of the table. In this way, we can deny access to corrupted or mismatching tables not only after crash recovery, but also after a clean shutdown.
