- * Optional CCB timeout handling.
- *
- * This code is useful for O/Ses that allow or expect
- * SIMs (low-level drivers) to handle SCSI IO timeouts.
- * It uses a power-of-two based algorithm of my own:)
- * that avoids scanning of lists, provided that:
- *
- * - The IO does complete in less than half the associated
- * timeout value.
- * - The greatest delay between the queuing of the IO and
- * its completion is less than
- * (1<<(SYM_CONF_TIMEOUT_ORDER_MAX-1))/2 ticks.
- *
- * For example, if tick is 1 second and the max order is 8,
- * any IO that is completed within less than 64 seconds will
- * just be put into some list at queuing and be removed
- * at completion without any additionnal overhead.
