Subject: [btrfs] 05fd9564e9: fio.write_iops 29.1% improvement
Greeting,
FYI, we noticed a 29.1% improvement of fio.write_iops due to commit:
commit: 05fd9564e9faf0f23b4676385e27d9405cef6637 ("btrfs: fix fallocate to use file_modified to update permissions consistently")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: fio-basic
on test machine: 96 threads 2 sockets Ice Lake with 256G memory
with following parameters:
runtime: 300s
disk: 1HDD
fs: btrfs
nr_task: 100%
test_size: 128G
rw: randwrite
bs: 4k
ioengine: ftruncate
cpufreq_governor: performance
ucode: 0xb000280
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.
test-url: https://github.com/axboe/fio
In addition to that, the commit also has significant impact on the following tests:

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.
