Subject: [locking/rwsem] 1b94536f2d: stress-ng.bad-altstack.ops_per_sec
-32.7% regression
Greeting,
FYI, we noticed a -32.7% regression of stress-ng.bad-altstack.ops_per_sec due to commit:
commit: 1b94536f2debc98260fb17b44f7f262e3336f7e0 ("locking/rwsem: Implement lock handoff to prevent lock starvation")
https://git.kernel.org/cgit/linux/kernel/git/tip/tip.git WIP.locking/core
in testcase: stress-ng
on test machine: 272 threads Intel(R) Xeon Phi(TM) CPU 7255 @ 1.10GHz with 112G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 5s
class: memory
cpufreq_governor: performance
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
