    block: track request size in blk_issue_stat · 88eeca49

    Currently there is no way to know the request size when the request is
    finished. Next patch will need this info. We could add extra field to
    record the size, but blk_issue_stat has enough space to record it, so
    this patch just overloads blk_issue_stat. With this, we will have 49bits
    to track time, which still is very long time.
