List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org Cc: Kevin Wolf , Benoit Canet , Stefan Hajnoczi There is a change in qemu-io sub-commands "aio_read" and "aio_write", which makes the aio requests accounted and the statistics reflected in blockstats. Note that IO throttling implementation allows overcommiting of requests, so the actual IO happened in a time unit may be a bit larger than given limits. In the test case, the stats numbers are compared against 110%, to make room for such flexibility in order to improve determinism. v4: Rebase to master. Add Benoit's rev-by lines to all the patches.
