[Qemu-devel] when to bdrv_co_flush()?

Hi, all bdrv_co_flush() will flush all cached data to persistent storage, and I'm wondering whether guest sync() will eventually trigger bdrv_co_flush() be called. Intuitively, guest sync() should trigger bdrv_co_flush() in qemu. But simple grep gave me a negative answer. So I'm wondering why
