Subject: [PATCH tip/core/rcu 14/27] rcu: Remove __maybe_unused from rcu_cpu_has_callbacks()
Date: Mon, 25 Jun 2018 17:35:00 -0700	[thread overview]
Message-ID: <20180626003513.27812-14-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20180626003448.GA26209@linux.vnet.ibm.com>

The rcu_cpu_has_callbacks() function is now used in all configurations,
so this commit removes the __maybe_unused.
