As part of MDEV-23855, we eliminated fil_system.LRU and changed the way how InnoDB data files are opened. We are also enforcing the innodb_open_files limit when new data files are created. The function fil_space_t::flush() would be invoked by row_quiesce_table_start(). If the table was already in clean state, it is possible that the data file is not open. fil_space_t::flush_low(): If the data file is not open, check with a debug assertion that there are no unflushed changes, and carry on.
