Description:
According to MySQL documentation from 5.7.9 the default for innodb_file_format_max is Barracuda but when we execute "mysqld --no-defaults --verbose --help" it shows Antelope. 

There are also another variables like innodb-buffer-pool-instances

How to repeat:
[root@centos_mysql ~]# mysqld --version
mysqld  Ver 5.7.21 for Linux on x86_64 (MySQL Community Server (GPL))

[root@centos_mysql ~]# mysqld --no-defaults --verbose --help | grep innodb-file-format-max
  --innodb-file-format-max[=name]
innodb-file-format-max                                       Antelope

[root@centos_mysql ~]# mysqld --no-defaults --verbose --help | grep innodb-buffer-pool-instances
  --innodb-buffer-pool-instances=#
innodb-buffer-pool-instances                                 0

[root@centos_mysql ~]# mysqld --no-defaults --verbose --help | grep innodb-io-capacity-max
  --innodb-io-capacity-max=#
innodb-io-capacity-max                                       18446744073709551615
