Subject: [LKP] [rcu]  7e28c5af4e:  will-it-scale.per_process_ops 84.7%
 improvement

Greeting,

FYI, we noticed a 84.7% improvement of will-it-scale.per_process_ops due to commit:


commit: 7e28c5af4ef6b539334aa5de40feca0c041c94df ("rcu: Eliminate ->rcu_qs_ctr from the rcu_dynticks structure")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master

in testcase: will-it-scale
on test machine: 288 threads Intel(R) Xeon Phi(TM) CPU 7295 @ 1.50GHz with 80G memory
with following parameters:

	nr_task: 100%
	mode: process
	test: brk1
	cpufreq_governor: performance

test-description: Will It Scale takes a testcase and runs it from 1 through to n parallel copies to see if the testcase will scale. It builds both a process and threads based test in order to see any differences between the two.
test-url: https://github.com/antonblanchard/will-it-scale



Details are as below:

To reproduce:

        git clone https://github.com/intel/lkp-tests.git
        cd lkp-tests
        bin/lkp install job.yaml  # job file is attached in this email
        bin/lkp run     job.yaml
