Subject: [Qemu-devel] [PATCH] Handle BH's queued by AIO completions in qemu_aio_flush()
Date: Mon, 20 Jul 2009 14:01:25 -0700 [thread overview]
Message-ID: <1248123685.4449.232.camel@voxel> (raw)
Without this, the call to qemu_aio_flush during migration doesn't
actually flush all in-flight SCSI IOs.
