Why off_t which is a signed value instead of the unsigned in passed in?

just use an on-stack array of type struct scsi_lun here, e.g.:
struct scsi_lun arr[RL_BUCKET_ELEMS];
Which you can then use directly instead of lun_p later, but which can
also be passed p_fill_from_dev_buffer as that takes a void pointer.
