* block: remove request ref_countChristoph Hellwig2017-04-111-7/+0
| | | | | | | | | | This reference count has been around since before git history, but the only place where it's used is in blk_execute_rq, and ther it is entirely useless as it is incremented before submitting the request and decremented in the end_io handler before waking up the submitter thread.
