Hello! This series applies some simplifications to RCU's callback-offloading code: 1. Remove rcu_is_nocb_cpu(), courtesy of Frederic Weisbecker. 2. Move rcu_nocb_is_setup to rcu_state, courtesy of Frederic Weisbecker. 3. Assume rcu_init() is called before smp, courtesy of Frederic Weisbecker. 4. Initialize boost kthread only for boot node prior SMP initialization, courtesy of Frederic Weisbecker. 5. Initialize nocb kthreads only for boot CPU prior SMP initialization, courtesy of Frederic Weisbecker. Thanx, Paul ------------------------------------------------------------------------ b/kernel/rcu/rcu.h | 2 -- b/kernel/rcu/tree.c | 11 +++++------ b/kernel/rcu/tree.h | 1 + b/kernel/rcu/tree_nocb.h | 8 -------- b/kernel/rcu/tree_plugin.h | 16 ---------------- kernel/rcu/tree.c | 11 +++++++++-- kernel/rcu/tree.h | 2 -- kernel/rcu/tree_nocb.h | 33 +++++---------------------------- 8 files changed, 20 insertions(+), 64 deletions(-)
