Subject: [linus:master] [mpage] 7d28631786: fio.write_iops 27.8% improvement
Greeting,
FYI, we noticed a 27.8% improvement of fio.write_iops due to commit:
commit: 7d28631786b2333c5d48ad25172eb159aaa2945f ("mpage: stop using bdev_{read,write}_page")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fio-basic
on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz (Cascade Lake) with 512G memory
with following parameters:
disk: 2pmem
fs: ext2
runtime: 200s
nr_task: 50%
time_based: tb
rw: randwrite
bs: 2M
ioengine: io_uring
test_size: 200G
cpufreq_governor: performance
test-description: Fio is a tool that will spawn a number of threads or processes doing a particular type of I/O action as specified by the user.

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.
