[f2fs] d4dd19ec1e: stress-ng.ioprio.ops_per_sec 418.8% improvement
by kernel test robot
Greeting,
FYI, we noticed a 418.8% improvement of stress-ng.ioprio.ops_per_sec due to commit:
commit: d4dd19ec1ea0cf6532d65709325c42b1398614a8 ("f2fs: do not expose unwritten blocks to user by DIO")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
in testcase: stress-ng
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 60s
fs: f2fs
class: filesystem
test: ioprio
cpufreq_governor: performance
ucode: 0x5003102
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.
