[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 |

[xfs] 6191cf3ad5: stress-ng.rename.ops_per_sec -73.5% regression
by kernel test robot
Greeting,
FYI, we noticed a -73.5% regression of stress-ng.rename.ops_per_sec due to commit:
commit: 6191cf3ad59fda5901160633fef8e41b064a5246 ("xfs: flush inodegc workqueue tasks before cancel")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads 2 sockets Ice Lake with 256G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: xfs
class: filesystem
test: rename
cpufreq_governor: performance
ucode: 0xb000280
In addition to that, the commit also has significant impact on the following tests:
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.

[PATCH v2 0/4] Fix softlockup when adding inotify watch
by Stephen Brennan
Hello,
I'd like to request re-testing this series on LKP, before posting my v2
more broadly. The 0-day bot detected a warning on my v1 posting[1]. I
believe v2 should address the warning but I'm still working on
reproducing it via the information included in the email. According to
the LKP website [2] it's possible to request testing by directly mailing
this list, so I wanted to try that in case I can't reproduce the
original.
[1]: https://lore.kernel.org/linux-fsdevel/[email protected]
[2]: https://01.org/lkp/documentation/0-day-test-service
Thanks,
Stephen
(series summary below)
When a system with large amounts of memory has several millions of
negative dentries in a single directory, a softlockup can occur while
adding an inotify watch:
watchdog: BUG: soft lockup - CPU#20 stuck for 9s! [inotifywait:9528]
CPU: 20 PID: 9528 Comm: inotifywait Kdump: loaded Not tainted 5.16.0-rc4.20211208.el8uek.rc1.x86_64 #1
Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.4.1 12/03/2020
RIP: 0010:__fsnotify_update_child_dentry_flags+0xad/0x120

v1 of this series can be found at:
https://lore.kernel.org/linux-fsdevel/20211214005337.161885-1-stephen.s.b...
v1 itself is based on a prior series:
https://lore.kernel.org/linux-fsdevel/1611235185-1685-1-git-send-email-ga...
The strategy employed by this series is to move negative dentries to the
end of the d_subdirs list, and mark them with a flag as "tail negative".
Then, readers of the d_subdirs list, which are only interested in
positive dentries, can stop reading once they reach the first tail
negative dentry. By applying this patch, I'm able to avoid the above
softlockup caused by 200 million negative dentries on my test system.
Inotify watches are set up nearly instantly.
Previously, Al expressed concern for:
1. Possible memory corruption due to use of lock_parent() in
sweep_negative(), see patch 01 for fix.
2. The previous patch didn't catch all ways a negative dentry could
become positive (d_add, d_instantiate_new), see patch 01.
3. The previous series contained a new negative dentry limit, which
capped the negative dentry count at around 3 per hash bucket. I've
dropped this patch from the series.
Patches 2-4 are unmodified from the previous posting.
Konstantin Khlebnikov (3):
fsnotify: stop walking child dentries if remaining tail is negative
dcache: add action D_WALK_SKIP_SIBLINGS to d_walk()
dcache: stop walking siblings if remaining dentries all negative
Stephen Brennan (1):
dcache: sweep cached negative dentries to the end of list of siblings

I'll call back in an hour
by Vlada
Hi,
I like a lot of things.. I just cannot list all of them here! But most of all..
My name is Vlada. http://earworks.com/?wptouch_switch=desktop&redirect=https%3A%2F%2Fyour-d... I like that I'm a woman, beautiful, shy and sometimes whimsical!
I do believe that I would meet a reliable, loving and wise man with whom I share all the moments in my life!
Is said that I am a tender, smart, with good sense of humor and honest girl.
I am modest, balanced and loving. I respect people and their personal freedom. I'd like to have a nice family of full value, but unfortunately I can't find a partner among people around me
Goodbye,
Vlada.

All my life I have been dreaming about a caring husband and happy children, everybody knows that for every woman the most important is family happiness. I would like to meet an honest.
I am a very nice, sensual girl, so I would love my man to be kind and sympathetic too. My Profiles:374074 - https://slackliner.de/wiki/?wptouch_switch=desktop&redirect=https%3A%2F%2...
My friends say that it is very difficult to resist my charm!
I like jogging, it helps me to keep in a good form. I am able to listen and to find the mutual language with different people. I am waiting for you! I'm just a lady who wants to find love!
Regards,
Zinaida.
