how to modify innodb_use_native_aio variable (no replies)

Hi All,

InnoDB now has a innodb_use_native_aio system variable that can be disabled at startup if there is a problem with the asynchronous I/O subsystem in the OS. This variable applies to Linux systems only, where the MySQL server now has a dependency on the libaio library.

How to disable that variable? In which file I have to modify the contents?
Or

If I want to modify the value of ‘innodb_use_native_aio’ where or in which file I have to change?

Thanks in Advance!!
