Subject: [non] 2aa3847085: will-it-scale.per_process_ops -32.0% regression
Greeting,
FYI, we noticed a -32.0% regression of will-it-scale.per_process_ops due to commit:
commit: 2aa38470853a65dc9b1b4bd0989d34cd3fc57ebd ("non-RCU analogue of the previous commit")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 4 threads Intel(R) Core(TM) i3-3220 CPU @ 3.30GHz with 4G memory
with following parameters:
test: open2
cpufreq_governor: performance
ucode: 0x21
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.

In addition to that, the commit also has significant impact on the following tests:
