Hello Ming,

The concept of dispatching does not have a meaning to block driver authors =
who are
not familiar with the block layer internals. However, every author of a blk=
-mq driver
knows what the .queue_rq() function is. Additionally, the new comment is gr=
ammatically
incorrect. So the above change looks like a step in the wrong direction to =
me.
