From dc3a04d551b5d21f1badbb39bfe8e5bc1289b184 Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Wed, 2 Sep 2015 17:11:22 -0700 Subject: [PATCH] security/device_cgroup: Fix RCU_LOCKDEP_WARN() condition f78f5b90c4ff ("rcu: Rename rcu_lockdep_assert() to RCU_LOCKDEP_WARN()") introduced a bug by incorrectly inverting the condition when moving from rcu_lockdep_assert() to RCU_LOCKDEP_WARN(). This commit therefore fixes the inversion. Reported-by: Felipe Balbi Reported-by: Tejun Heo Signed-off-by: Paul E.
