It's a serious bug that the vhost-user will lose the reconnect forever. The 2nd patch enhances the error handle of vhost-user-scsi. This patchset's parent commit is: https://lore.kernel.org/all/20230731121018.2856310-1-fengli@smartx.com/ Changes for v2: - Add a event_cb in VhostAsyncCallback to be called when dev is NULL; - Fix the error report message.
