Subject: [PATCH tip/core/rcu 06/12] rcu: Remove unused rcu_cpu_kthread_cpu per-CPU variable
Date: Wed, 9 Jan 2019 13:28:28 -0800 [thread overview]
Message-ID: <20190109212834.1257-6-paulmck@linux.ibm.com> (raw)
In-Reply-To: <20190109212816.GA32282@linux.ibm.com>
The rcu_cpu_kthread_cpu used to provide debugfs information, but is no
longer used. This commit therefore removes it.
