Subject: [lkp-robot] [fs] 3deb642f0d: will-it-scale.per_process_ops -8.8%
regression
Greeting,
FYI, we noticed a -8.8% regression of will-it-scale.per_process_ops due to commit:
commit: 3deb642f0de4c14f37437dd247f9c77839f043f8 ("fs: introduce new ->get_poll_head and ->poll_mask methods")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 32 threads Intel(R) Xeon(R) CPU E5-2680 0 @ 2.70GHz with 64G memory
with following parameters:
test: poll2
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
