[MDEV-10917] Warning suggesting that innodb_page_size is experimental may be inaccurate Created: 2016-09-28  Updated: 2016-10-29  Resolved: 2016-10-29

 Description   

If a user sets something like the following in their configuration file:

innodb_page_size=64k

Then they will see a warning like the following in their error log:

InnoDB: Warning: innodb_page_size has been changed from default value 16384 to 65536d. (###EXPERIMENTAL### operation)

But the documentation seems to imply that this option is no longer experimental, since Percona's experimental version was replaced with the version from MySQL 5.6.

Is this warning inaccurate? If so, the "experimental" reference should probably be removed.

It looks like MariaDB 10.0 does not mention the word "experimental" in the message it prints to the error log:

2016-09-28 14:27:11 7f39475c4880 InnoDB: innodb-page-size has been changed from the default value 16384 to 8192.

Was the "experimental" wording intentionally added in MariaDB 10.1, or did it somehow return from Percona's experimental version of innodb_page_size from MariaDB 5.5?
