From c839e7a03f92bafd71fd145b470dcdc7f43f2d4c Mon Sep 17 00:00:00 2001 From: "Dennis Zhou (Facebook)" Date: Tue, 11 Sep 2018 14:41:33 -0400 Subject: blkcg: remove bio->bi_css and instead use bio->bi_blkg Prior patches ensured that all bios are now associated with some blkg. This now makes bio->bi_css unnecessary as blkg maintains a reference to the blkcg already. This patch removes the field bi_css and transfers corresponding uses to access via bi_blkg.
