Subject: [mm] 974b9b2c68: will-it-scale.per_process_ops -1.8% regression
Greeting,
FYI, we noticed a -1.8% regression of will-it-scale.per_process_ops due to commit:
commit: 974b9b2c68f3d35a65e80af9657fe378d2439b60 ("mm: consolidate pte_index() and pte_offset_*() definitions")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 104 threads Skylake with 192G memory
with following parameters:
nr_task: 100%
mode: process
test: brk1
cpufreq_governor: performance
ucode: 0x2000065
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
If you fix the issue, kindly add following tag
