rcu/nocb: Reduce ->nocb_lock contention with separate ->nocb_gp_lock The sleep/wakeup of the no-CBs grace-period kthreads is synchronized using the ->nocb_lock of the first CPU corresponding to that kthread. This commit provides a separate ->nocb_gp_lock for this purpose, thus reducing contention on ->nocb_lock. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com>
