[af_unix] afd20b9290: stress-ng.sockdiag.ops_per_sec -26.3% regression
by kernel test robot
Greeting,
FYI, we noticed a -26.3% regression of stress-ng.sockdiag.ops_per_sec due to commit:
commit: afd20b9290e184c203fe22f2d6b80dc7127ba724 ("af_unix: Replace the big lock with small locks.")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: stress-ng
on test machine: 128 threads 2 sockets Intel(R) Xeon(R) Platinum 8358 CPU @ 2.60GHz with 128G memory
with following parameters:
nr_threads: 100%
testtime: 60s
class: network
test: sockdiag
cpufreq_governor: performance
ucode: 0xd000280
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang(a)intel.com>
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
sudo bin/lkp install job.yaml # job file is attached in this email
bin/lkp split-job --compatible job.yaml # generate the yaml file for lkp run
sudo bin/lkp run generated-yaml-file
# if come across any failure that blocks the test,
# please remove ~/.lkp and /lkp dir to run from a clean state.

[memcg] 0f12156dff: will-it-scale.per_process_ops -33.6% regression
by kernel test robot
Greeting,
FYI, we noticed a -33.6% regression of will-it-scale.per_process_ops due to commit:
commit: 0f12156dff2862ac54235fc72703f18770769042 ("memcg: enable accounting for file lock caches")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: will-it-scale
on test machine: 104 threads 2 sockets Skylake with 192G memory
with following parameters:
nr_task: 50%
mode: process
test: lock1
cpufreq_governor: performance
ucode: 0x2006a0a
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
In addition to that, the commit also has significant impact on the following tests:
+------------------+---------------------------------------------------------------------------------+
| testcase: change | will-it-scale: will-it-scale.per_process_ops -40.9% regression |
| test machine | 128 threads 2 sockets Intel(R) Xeon(R) Gold 6338 CPU @ 2.00GHz with 256G memory |
| test parameters | cpufreq_governor=performance |
| | mode=process |
| | nr_task=50% |
| | test=lock1 |
| | ucode=0xd000280 |

Not being CC'd on reports for commits from my tree authored by somebody else
by Vlastimil Babka
Hi,
LKP tests branches my kernel.org tree(s) but it seems if the commit is
authored by somebody else, I'm not CC'd directly, even though there's my
Signed-off-by and it's in my git tree.
Example:
https://lore.kernel.org/all/[email protected]/
I would like to be CC'd in such cases. Can you perhaps just Cc additionally
based on Signed-off-by for everyone? Or if some other maintaners don't want
this, do it at least for my trees:
https://git.kernel.org/cgit/linux/kernel/git/vbabka/linux.git
https://git.kernel.org/cgit/linux/kernel/git/vbabka/slab.git
Thanks a lot!
