struct scsi_cmnd * scmd
Original SCSI cmd that eh has finished.
struct list_head * done_q
Queue for processed commands.
We don't want to use the normal command completion while we are are still handling errors - it may cause other commands to be queued, and that would disturb what we are doing. Thus we really want to keep a list of pending commands for final completion, and once we are ready to leave error handling we handle completion for real.
