Subject: [PATCH tip/core/rcu 09/10] rcu: Replace synchronize_sched_expedited_wait() "_sched" with "_rcu"
Date: Mon, 9 Dec 2019 20:01:53 -0800 [thread overview]
Message-ID: <20191210040154.2498-9-paulmck@kernel.org> (raw)
In-Reply-To: <20191210040122.GA2419@paulmck-ThinkPad-P72>
From: "Paul E. McKenney" <paulmck@kernel.org>
After RCU flavor consolidation, synchronize_sched_expedited_wait() does
both RCU-preempt and RCU-sched, whichever happens to have been built into
the running kernel. This commit therefore changes this function's name
to synchronize_rcu_expedited_wait() to reflect its new generic nature.
