From 5ed42b8113667c06a6ff2c72717395b5044d30a1 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 3 Mar 2010 07:46:58 -0800 Subject: [PATCH] rcu, cgroup: Relax the check in task_subsys_state() as early boot is now handled by lockdep-RCU This patch removes the check for !rcu_scheduler_active because this check has been incorporated into rcu_dereference_check().
