Subject: [locking/rwsem] 7813430057: vm-scalability.median -42.5% regression
Greeting,
FYI, we noticed a -42.5% regression of vm-scalability.median due to commit:
commit: 78134300579a45f527ca173ec8fdb4701b69f16e ("locking/rwsem: Don't call owner_on_cpu() on read-owner")
https://kernel.googlesource.com/pub/scm/linux/kernel/git/torvalds/linux.git master
in testcase: vm-scalability
on test machine: 88 threads Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz with 128G memory
with following parameters:
runtime: 300s
test: small-allocs-mt
cpufreq_governor: performance
ucode: 0xb000036
test-description: The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
test-url: https://git.kernel.org/cgit/linux/kernel/git/wfg/vm-scalability.git/
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
