From 95fe6c1a209ef89d9f94dd04a0ad72be1487d5d5 Mon Sep 17 00:00:00 2001 From: Mike Christie Date: Sun, 5 Jun 2016 14:31:48 -0500 Subject: block, fs, mm, drivers: use bio set/get op accessors This patch converts the simple bi_rw use cases in the block, drivers, mm and fs code to set/get the bio operation using bio_set_op_attrs/bio_op These should be simple one or two liner cases, so I just did them in one patch. The next patches handle the more complicated cases in a module per patch.
