rcu: Distinguish between NOCB and non-NOCB rcu_callback trace events One way to distinguish between NOCB and non-NOCB rcu_callback trace events is that the former always print zero for the lazy and non-lazy queue lengths. Unfortunately, this also means that we cannot see the NOCB queue lengths. This commit therefore accesses the NOCB queue lengths, but negates them. NOCB rcu_callback trace events should therefore have negative queue lengths. Signed-off-by: Paul E.
