    Description

      hi, i need information about locks in tables, and locks of GET_LOCK
      how could i get this information via information_schema plugin?
      what i need:

      table_locks:
      database, table, thread (connection), lock type (write/read), lock_create_time

      get_locks:
      lock_name, locked, thread(connection), lock_duration, lock_create_time

      i was reading mariadb 10.0.2 and it use a MDL maybe it's a abstract lock right? there's more usefull information that MDL can expose?
