Greeting,
FYI, we noticed a 248.5% improvement of stress-ng.rename.ops_per_sec due to commit:
commit: 1e3a7e46a47e6a53068fb9bee539daf78105fb4b ("[PATCH 2/2] xfs: introduce xfs_inodegc_push()")
url: https://github.com/intel-lab-lkp/linux/commits/Dave-Chinner/xfs-non-blocking-inodegc-pushes/20220524-144000
base: https://git.kernel.org/cgit/fs/xfs/xfs-linux.git for-next
patch link: https://lore.kernel.org/linux-xfs/[email protected]
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
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.
