From 9ecf4866c018aeb304a7b49216c4d183665becb7 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Fri, 22 May 2015 17:13:54 -0400 Subject: writeback: make bdi_start_background_writeback() take bdi_writeback instead of backing_dev_info bdi_start_background_writeback() currently takes @bdi and kicks the root wb (bdi_writeback). In preparation for cgroup writeback support, make it take wb instead. This patch doesn't make any functional difference.
