Hi,

I've just figured out after installing MariaDB 5.5.23 on two server (one
directly from the x64 binary, and the other using the debian packing)
that innodb_use_native_aio is OFF on the two servers.
Before upgrading to MariaDB, I was using percona
5.5.21-rel25.1-234.squeeze, and innodb_use_native_aio was properly used.
There's nothing wrong reported in the MySQL log.

The log with percona 5.5.21 :

120425  3:55:46 InnoDB: The InnoDB memory heap is disabled
120425  3:55:46 InnoDB: Mutexes and rw_locks use GCC atomic builtins

The log with mariadb 5.5.23 :

120425  3:41:04 InnoDB: The InnoDB memory heap is disabled
120425  3:41:04 InnoDB: Mutexes and rw_locks use GCC atomic builtins

120425  3:41:09 Percona XtraDB (http://www.percona.com) 1.1.8-24.1
started; log sequence number 33812411088

(no more line saying Linux native AIO is used)

Am I missing something ?

Thanks and regards,
  Jocelyn Fournier
