Subject: [PATCH tip/core/rcu 13/12] Remove wrapper definitions for obsolete RCU update functions
Date: Thu, 10 Jan 2019 15:37:04 -0800 [thread overview]
Message-ID: <20190110233704.GA27112@linux.ibm.com> (raw)
In-Reply-To: <20190109211830.GA30595@linux.ibm.com>
None of synchronize_rcu_bh, synchronize_rcu_bh_expedited, call_rcu_bh,
rcu_barrier_bh, synchronize_sched, synchronize_sched_expedited,
call_rcu_sched, rcu_barrier_sched, get_state_synchronize_sched, and
cond_synchronize_sched are actually used. This commit therefore removes
their trivial wrapper-function definitions.
Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com>
[ paulmck: The intent was to defer this to the following release, but
there are no more uses of these functions, so full speed ahead!!! ]
