| |
Hello!
This series contains minor response-time improvements.
1. Create trivial always-true version of rcu_is_nocb_cpu() for CONFIG_RCU_NOCB_CPU_ALL=y kernels.
2. Create trivial always-false version of rcu_needs_cpu() for CONFIG_RCU_NOCB_CPU_ALL=y kernels.
3. Don't bother doing CONFIG_RCU_FAST_NO_HZ work at idle entry and exit time for CONFIG_RCU_NOCB_CPU_ALL=y kernels.
Thanx, Paul
