Subject: [filemap] 5ccc944dce:
phoronix-test-suite.fio.SequentialRead.POSIXAIO.Yes.Yes.4KB.DefaultTestDirectory.mb_s
-8.5% regression
(please be noted we reported
"[filemap] 91fd26c76b: phoronix-test-suite.fio.SequentialRead.LinuxAIO.Yes.No.4KB.DefaultTestDirectory.mb_s -8.9% regression"
on
https://lore.kernel.org/all/Yrl0ucIqhZA75%2FkO@xsang-OptiPlex-9020/
now we noticed this commit is merged into mainline and the regression is still
existing. Just FYI)
Greeting,
FYI, we noticed a -8.5% regression of phoronix-test-suite.fio.SequentialRead.POSIXAIO.Yes.Yes.4KB.DefaultTestDirectory.mb_s due to commit:
commit: 5ccc944dce3df5fd2fd683a7df4fd49d1068eba2 ("filemap: Correct the conditions for marking a folio as accessed")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: phoronix-test-suite
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
test: fio-1.14.1
option_a: Sequential Read
option_b: POSIX AIO
option_c: Yes
option_d: Yes
option_e: 4KB
option_f: Default Test Directory
cpufreq_governor: performance
ucode: 0x500320a
test-description: The Phoronix Test Suite is the most comprehensive testing and benchmarking platform available that provides an extensible framework for which new tests can be easily added.

Reported-by: kernel test robot <oliver.sang@...el.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.
