Subject: [PATCH tip/core/rcu 08/11] rcu/nocb: Rename rcu_organize_nocb_kthreads() local variable
Date: Thu, 1 Aug 2019 15:50:25 -0700 [thread overview]
Message-ID: <20190801225028.18225-8-paulmck@linux.ibm.com> (raw)
In-Reply-To: <20190801225009.GA17155@linux.ibm.com>
This commit renames rdp_leader to rdp_gp in order to account for the
new distinction between callback and grace-period no-CBs kthreads.
