From 1eff9d322a444245c67515edb52bc0eb68374aa8 Mon Sep 17 00:00:00 2001 From: Jens Axboe Date: Fri, 5 Aug 2016 15:35:16 -0600 Subject: 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.
