From 10ccd84695c2a03075bad2f4fc728575fe9051f8 Mon Sep 17 00:00:00 2001 From: Tejun Heo Date: Tue, 19 Oct 2010 11:08:41 +0200 Subject: memory_hotplug: drop spurious calls to flush_scheduled_work() lru_add_drain_all() uses schedule_on_each_cpu() which is synchronous. There is no reason to call flush_scheduled_work() after lru_add_drain_all(). Drop the spurious calls. This is to prepare for the deprecation and removal of flush_scheduled_work().
