Hi,

The commit also causes -74.6% regression of will-it-scale.per_thread_ops:

in testcase: will-it-scale
on test machine: 8 threads Intel(R) Core(TM) i7-3770K CPU @ 3.50GHz with 16G memory
with following parameters:

nr_task: 100%
mode: thread
test: unlink2
cpufreq_governor: performance
ucode: 0x21

I'll send another report for this regression.

Best Regards,
Rong Chen
