Hello,

This series contains SRCU updates:

1.      Remove superfluous callbacks advancing from srcu_gp_start(),
        courtesy of Frederic Weisbecker.

2.      No need to advance/accelerate if no callback enqueued, courtesy
        of Frederic Weisbecker.

3.      Explain why callbacks invocations can't run concurrently,
        courtesy of Frederic Weisbecker.


Thanks
Neeraj
