From: Wangyong <[email protected]> Since commit 6040aedddb5f474a9c2304b6a432a652d82b3d3c "virtio-blk: make queue size configurable",if the user set the queue size to more than 128 ,it will not take effect. That's because linux aio's maximum outstanding requests at a time is always less than or equal to 128.
This patch simply increase MAX_EVENTS to a larger hardcoded value of 1024 as a shortterm fix.
