charset="utf-8" Instead of calling into scsi_handle_rw_error() directly from scsi_block_sgio_complete() and skipping the normal callback, go through the normal cleanup path by calling the callback with a positive error value. The important difference here is not only that the code path is cleaner, but that the callbacks set r->req.aiocb =3D NULL. If we skip setting this and the error action is BLOCK_ERROR_ACTION_STOP, resuming the VM runs into an assertion failure in scsi_read_data() or scsi_write_data() because the dangling aiocb pointer is unexpected.
