From 922453bca6a927bb527068ae8679d587cfa45dbc Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Wed, 30 Nov 2011 12:23:43 +0000 Subject: block: convert qemu_aio_flush() calls to bdrv_drain_all() Many places in QEMU call qemu_aio_flush() to complete all pending asynchronous I/O. Most of these places actually want to drain all block requests but there is no block layer API to do so. This patch introduces the bdrv_drain_all() API to wait for requests across all BlockDriverStates to complete. As a bonus we perform checks after qemu_aio_wait() to ensure that requests really have finished.
