[xfs] 016a23388c: stress-ng.xattr.ops_per_sec 58.4% improvement
by kernel test robot
Greeting,
FYI, we noticed a 58.4% improvement of stress-ng.xattr.ops_per_sec due to commit:
commit: 016a23388cdcb2740deb1379dc408f21c84efb11 ("xfs: Add order IDs to log items in CIL")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.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: xattr
cpufreq_governor: performance
ucode: 0xb000280
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.

[selftests] a37ddddd86: BUG:KASAN:use-after-free_in_firmware_upload_unregister
by kernel test robot
Greeting,
FYI, we noticed the following commit (built with gcc-11):
commit: a37ddddd86037c896c702b4df416bc4e51b2a5a0 ("selftests: firmware: Add firmware upload selftests")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: kernel-selftests
version: kernel-selftests-x86_64-4cb0bec3-1_20220724
with following parameters:
group: firmware
ucode: 0xec
test-description: The kernel contains a set of "self tests" under the tools/testing/selftests/ directory. These are intended to be small unit tests to exercise individual code paths in the kernel.
test-url: https://www.kernel.org/doc/Documentation/kselftest.txt
on test machine: 8 threads Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with 28G memory
caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace):
If you fix the issue, kindly add following tag

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.
