Subject: [xfs] bbffdbb4a4: filebench.sum_bytes_mb/s -47.7% regression
Greeting,
FYI, we noticed a -47.7% regression of filebench.sum_bytes_mb/s due to commit:
commit: bbffdbb4a4296717b3db5963dda4da72a06876de ("xfs: deferred inode inactivation")
https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git repair-hard-problems
in testcase: filebench
on test machine: 8 threads Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz with 8G memory
with following parameters:
disk: 1HDD
fs: xfs
test: fileserver.f
cpufreq_governor: performance
ucode: 0x27
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <rong.a.chen@...el.com>
Details are as below:
