commit d4366c4a2c9b41901b11ca180d3ddbf79e992490

Please send commit emails next time. This time I had to go and download the patch from github and paste it in an email.

Just remove mark_trx_read_write() from ha_create_partitioning_metadata(). It's a non-transactional operation anyway. It's always a part of DDL, so will have the same protection as DDL does.

return create_partitioning_metadata(name, old_name, action_flag); }
