-/**
- * blk_queue_bounce_pfn - set the bounce buffer limit for queue
- * @q: the request queue for the device
- * @pfn: max address
- *
- * Description:
- * This function is similar to blk_queue_bounce_limit except it
- * neither changes allocation flags, nor does it set up the ISA DMA
- * pool. This function should only be used by stacking drivers.
- * Hardware drivers should use blk_queue_bounce_limit instead.
