Joel Fernandes (Google) 3afe7fa535 rcu/trace: Add tracing for how segcb list changes ... This commit adds tracing to track how the segcb list changes before/after acceleration, during queuing and during dequeuing. This tracing helped discover an optimization that avoided needless GP requests when no callbacks were accelerated. The tracing overhead is minimal as each segment's length is now stored in the respective segment.
