Please read the entire thread. blk_queue_max_hw_sectors() is dead, it was never used except briefly by DM. Device drivers should use blk_queue_max_sectors() to set their hard limit. max_sectors is a block layer soft limit that can be overridden on a per-device basis in /sys/block/foo/queue/max_sectors_kb. -- Martin K.
