Thus, the next time the scsi_cmnd structure is used, the command may fail in scsi_cmd_runtime_exceeded() due to the old jiffies_at_alloc value: kernel: sd 16:0:1:84: [sdts] tag#405 timing out command, waited 720s kernel: sd 16:0:1:84: [sdts] tag#405 FAILED Result: hostbyte=DID_OK driverbyte=DRIVER_OK cmd_age=66636s Clear flags for commands that have not been completed by SCSI.
