Block drivers typically have two copies of the flush operation: a synchronous .bdrv_flush() and an asynchronous .bdrv_aio_flush(). This patch applies the same emulation that we already do for .bdrv_read()/.bdrv_write() to .bdrv_flush(). Now block drivers only need to provide either .bdrv_aio_flush() or, in the case of legacy drivers, .bdrv_flush().
I had the same bug in my nbd improvements series, so thanks. After Kevin merges this and parts 1-7 (or 1-9 even) of that series I'll resend.
