* Handle the following kernel commit:
*
* commit 1eff9d322a444245c67515edb52bc0eb68374aa8
* Author: Jens Axboe <axboe@fb.com>
* Date: Fri Aug 5 15:35:16 2016 -0600
*
* block: rename bio bi_rw to bi_opf
*
* Since commit 63a4cc24867d, bio->bi_rw contains flags in the lower
* portion and the op code in the higher portions. This means that
* old code that relies on manually setting bi_rw is most likely
* going to be broken. Instead of letting that brokeness linger,
* rename the member, to force old and out-of-tree code to break
* at compile time instead of at runtime.
*
* No intended functional changes in this commit.
