From: Alan Stern <stern@rowland.harvard.edu> This patch (as559b) adds a new routine, scsi_unprep_request, which gets called every place a request is requeued. (That includes scsi_queue_insert as well as scsi_requeue_command.) It also changes scsi_kill_requests to make it call __scsi_done with result equal to DID_NO_CONNECT << 16. (I'm not sure if it's necessary to call scsi_init_cmd_errh here; maybe you can check on that.) Finally, the patch changes the return value from scsi_end_request, to avoid returning a stale pointer in the case where the request was requeued. Fortunately the return value is used in only place, and the change actually simplified it.
