From a0265a7f5161b6cb55e82b71edb236bbe0d9b3ae Mon Sep 17 00:00:00 2001 From: Tejun Heo <tj@kernel.org> Date: Tue, 19 Mar 2013 13:55:42 -0700
699ce097efe ("workqueue: implement and use pwq_adjust_max_active()") replaced the only workqueue_freezing usage outside freezer callbacks with a POOL_FREEZING test. This makes workqueue_freezing unused when !CONFIG_FREEZER leading to a compiler warning. Define workqueue_freezing iff CONFIG_FREEZER.
