Fusion-io Multi-threaded Flush

MariaDB has a number of significant performance gains on Fusion-io devices (introduced with the 10.0.9 Fusion-io preview).
After adding a new page type and improving the underlying storage system, it was noted that InnoDB page flushing does not scale well. This is because InnoDB page flushing is single threaded. The solution was to introduce multi-threaded flush.
To enable, set innodb_use_mtflush and innodb_mtflush_threads (default is 8).
innodb_use_mtflush=1 innodb_mtflush_threads=8
