Wrong value about innodb_buffer_pool_instances with MySQL 5.6

[stonio]

Wrong information about innodb_buffer_pool_instances using MySQL 5.6:

-------- InnoDB Metrics ----------------------------------------------------------------------------
[--] InnoDB is enabled.
[--] InnoDB Buffers
[--]  +-- InnoDB Buffer Pool: 128.0M
[--]  +-- InnoDB Buffer Pool Instances: 8
[--]  +-- InnoDB Additional Mem Pool: 8.0M



Variables to adjust:
    innodb_buffer_pool_instances (=1)

However, this variable is already set to default value 1.
If you read note in MySQL 5.6 Reference Manual:

A bug in MySQL 5.6 causes SHOW VARIABLES to report an innodb_buffer_pool_instances value of 8 when innodb_buffer_pool_size is less than 1GB and only one buffer pool instance is present (Bug #18343670).
