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
