Not sure what you're referring to. If you mean iscsi_aio_cancel(), isn't it dead code anyway since we changed block.c to use coroutines for everything? bdrv_co_io_em() even throws the acb away, so even if you wanted, there's no way to cancel the request even today. And the lines deleted/inserted are much in favour of this patch. Kevin
