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 ------------------------------------------------------------------------ b/kernel/rcu/srcutree.c | 10 ---------- kernel/rcu/srcutree.c | 14 +++++++++++--- 2 files changed, 11 insertions(+), 13 deletions(-)
