Subject: [LKP] [mm] 9bc8039e71: will-it-scale.per_thread_ops -64.1%
regression
Greeting,
FYI, we noticed a -64.1% regression of will-it-scale.per_thread_ops due to commit:
commit: 9bc8039e715da3b53dbac89525323a9f2f69b7b5 ("mm: brk: downgrade mmap_sem to read when shrinking")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 8 threads Ivy Bridge with 16G memory
with following parameters:
nr_task: 100%
mode: thread
test: brk1
ucode: 0x20
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
