ata_scsi_rbuf_fill - wrapper for SCSI command simulators

void ata_scsi_rbuf_fill(struct ata_scsi_args *  args , unsigned int (* actor ) (struct ata_scsi_args *args, u8 *rbuf));

args
    device IDENTIFY data / SCSI command of interest.

actor
    Callback hook for desired SCSI command simulator

Takes care of the hard work of simulating a SCSI command... Mapping the response buffer, calling the commandAqs handler, and handling the handlerAqs 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).
