/**
* blk_queue_alignment_offset - set physical block alignment offset
* @q: the request queue for the device
- * @alignment: alignment offset in bytes
+ * @offset: alignment offset in bytes
*
* Description:
* Some devices are naturally misaligned to compensate for things like
/**
* blk_queue_io_min - set minimum request size for the queue
* @q: the request queue for the device
- * @io_min: smallest I/O size in bytes
+ * @min: smallest I/O size in bytes
*
* Description:
* Some devices have an internal block size bigger than the reported
/**
* blk_queue_io_opt - set optimal request size for the queue
* @q: the request queue for the device
- * @io_opt: optimal request size in bytes
+ * @opt: optimal request size in bytes
*
* Description:
* Drivers can call this function to set the preferred I/O request
/**
* blk_stack_limits - adjust queue_limits for stacked devices
* @t: the stacking driver limits (top)
- * @bdev: the underlying queue limits (bottom)
+ * @b: the underlying queue limits (bottom)
* @offset: offset to beginning of data within component device
*
* Description:
