blkcg: Drop unnecessary RCU read [un]locks from blkg_conf_prep/finish() Now that all RCU flavors have been combined either holding a spin lock, disabling irq or disabling preemption implies RCU read lock, so there's no need to use rcu_read_[un]lock() explicitly while holding queue_lock. This shouldn't cause any behavior changes. v2: Description updated. Leave __acquires/release on queue_lock alone. Signed-off-by: Tejun Heo <tj@kernel.org>
