dict_table_open_on_id(): Simplify the logic. dict_stats: A helper for acquiring MDL and opening the tables mysql.innodb_table_stats and mysql.innodb_index_stats. innodb_ft_aux_table_validate(): Contiguously hold dict_sys.latch while accessing the table that we open with dict_table_open_on_name(). lock_table_children(): Do not hold a table reference while invoking dict_acquire_mdl_shared<false>(), which may temporarily release and reacquire the shared dict_sys.latch that we are holding. With these changes, no caller of dict_acquire_mdl_shared<false> should be holding a table reference. All remaining calls to dict_table_open_on_name(dict_locked=false) except the one in fts_lock_table() and possibly in the DDL recovery predicate innodb_check_version() should be protected by MDL, but there currently is no assertion that would enforce this.
