From: Miaohe Lin <linmiaohe@xxxxxxxxxx> [ Upstream commit da63dc84befaa9e6079a0bc363ff0eaa975f9073 ] Compaction sysfs file is created via compaction_register_node in register_node. But we forgot to remove it in unregister_node. Thus compaction sysfs file is leaked. Using compaction_unregister_node to fix this issue.
