Now that RCU can have readers with multiple segments, it is quite possible that a specific sequence of reader segments might result in an rcutorture failure (reader spans a full grace period as detected by one of the grace-period primitives) or an rcutorture close call (reader potentially spans a full grace period based on reading out the RCU implementation's grace-period counter, but with no ordering). In such cases, it would clearly ease debugging if the offending specific sequence was known. For the first reader encountering a failure or a close call, this commit therefore dumps out the segments, delay durations, and whether or not the reader was preempted. Signed-off-by: Paul E.
