Hi Paul,
We are pleased to notice huge throughput increases in the qperf/iperf tests, together with noticeable reduce of power consumption!
git://git.kernel.org/pub/scm/linux/kernel/git/paulmck/linux-rcu.git rcu/dev commit 34577530114e9b1de10f3aa9665bb28c8ce585ba ("rcu: Bind grace-period kthreads to non-NO_HZ_FULL CPUs")
