MDEV-28772 Mariabackup locks database for minutes since 10.8.3
mariadb-backup: Add the Boolean option --innodb-log-file-buffering
(default ON) to control whether the server's ib_logfile0 should be
accessed via the file system cache during --backup. We may be retrying
reads of the last log block very frequently, which may cause I/O stalls
when the file system cache is being bypassed.
This addresses a regression that was introduced in
commit 4c0cd953abffea841271f3a5cce1712d5e6c5633 (MDEV-28766).
On some affected systems, it may make sense to additionally
SET GLOBAL innodb_log_file_buffering=OFF on the server for the
duration of making a backup.
