rcu: Eliminate in_irq() checks in rcu_enter_nohz() The in_irq() check in rcu_enter_nohz() is redundant because if we really are in an interrupt, the attempt to re-enter dyntick-idle mode will invoke rcu_needs_cpu() in any case, which will force the check for RCU callbacks. So this commit removes the check along with the set_need_resched(). Suggested-by: Frederic Weisbecker <fweisbec@gmail.com> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
