rcu: Make rcu_start_this_gp() check for out-of-range requests If rcu_start_this_gp() is invoked with a requested grace period more than three in the future, then either the ->need_future_gp[] array needs to be bigger or the caller needs to be repaired. This commit therefore adds a WARN_ON_ONCE() checking for this condition. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Tested-by: Nicholas Piggin <npiggin@gmail.com>
