Also fixes MDEV-23929: innodb_flush_neighbors is not being ignored for system tablespace on SSD When the maximum configured number of file is exceeded, InnoDB will close data files. We used to maintain a fil_system.LRU list and a counter fil_node_t::n_pending to achieve this, at the huge cost of multiple fil_system.mutex operations per I/O operation. fil_node_open_file_low(): Implement a FIFO replacement policy: The last opened file will be moved to the end of fil_system.space_list, and files will be closed from the start of the list. However, we will not move tablespaces in fil_system.space_list while i_s_tablespaces_encryption_fill_table() is executing (producing output for INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION) because it may cause information of some tablespaces to go missing. We also avoid this in mariabackup --backup because datafiles_iter_next() assumes that the ordering is not changed. IORequest: Fold more parameters to IORequest::type. fil_space_t::io(): Replaces fil_io(). fil_space_t::flush(): Replaces fil_flush(). OS_AIO_IBUF: Remove. We will always issue synchronous reads of the change buffer pages in buf_read_page_low(). We will always ignore some errors for background reads. This should reduce fil_system.mutex contention a little. fil_node_t::complete_write(): Replaces fil_node_t::complete_io(). On both read and write completion, fil_space_t::release_for_io() will have to be called. fil_space_t::io(): Do not acquire fil_system.mutex in the normal code path. xb_delta_open_matching_space(): Do not try to open the system tablespace which was already opened. This fixes a file sharing violation in mariabackup --prepare --incremental. Reviewed by: Vladislav Vaintroub
