DESCRIPTION¶
Takes care of the hard work of simulating a SCSI command... Mapping the response buffer, calling the command´s handler, and handling the handler´s return value. This return value indicates whether the handler wishes the SCSI command to be completed successfully (0), or not (in which case cmd->result and sense buffer are assumed to be set).
