Subject: [btrfs] 639bd575b7: stress-ng.fallocate.ops_per_sec 29.2% improvement
Greeting,
FYI, we noticed a 29.2% improvement of stress-ng.fallocate.ops_per_sec due to commit:
commit: 639bd575b7c7fa326abadd2ef3e374a5a24eb40b ("btrfs: fix race leading to unnecessary transaction commit when logging inode")
https://git.kernel.org/cgit/linux/kernel/git/kdave/linux.git for-5.11
in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory
with following parameters:
nr_threads: 10%
disk: 1HDD
testtime: 30s
class: filesystem
cpufreq_governor: performance
ucode: 0x5003003
fs: btrfs
Details are as below:
-------------------------------------------------------------------------------------------------->
To reproduce:
git clone https://github.com/intel/lkp-tests.git
cd lkp-tests
bin/lkp install job.yaml # job file is attached in this email
bin/lkp run job.yaml
