 Description   

Some useless fields have been added to dict_table_t as part of the encryption work in MariaDB Server 10.1.
These redundant fields may cause race conditions or inconsistencies. The fields include:
dict_table_t::thd
dict_table_t::page_0_read (this one is completely unused!)
dict_table_t::crypt_data
