Description:
On Mac OS X, executing a REORGANIZE PARTITION statement will change the name of the table to lowercase.

How to repeat:
Start mysql with lower_case_table_names = 2 on Mac OS X.

create database foo;
use foo;
create table camelCase (id int, data varchar(20));
alter table camelCase partition by range (id) (partition p0 values less than (0), partition p1 values less than (MAXVALUE));

show tables; -- observe the table is named camelCase

alter table camelCase reorganize partition p1 into (partition p1 values less than (1000), partition p2 values less than (MAXVALUE));

show tables; -- observe the table is now named camelcase
