From 89f3b6d62f2c7c1ed7b2e672be605016d9ff60f2 Mon Sep 17 00:00:00 2001 From: Pavel Begunkov Date: Sat, 14 Sep 2019 20:31:50 +0300 Subject: bfq: Fix bfq linkage error Since commit 795fe54c2a828099e ("bfq: Add per-device weight"), bfq uses blkg_conf_prep() and blkg_conf_finish(), which are not exported. So, it causes linkage error if bfq compiled as a module.
