Subject: [xfs] f4da454e15: stress-ng.dentry.ops_per_sec -36.8% regression
Greeting,
FYI, we noticed a -36.8% regression of stress-ng.dentry.ops_per_sec due to commit:
commit: f4da454e1584a4d1d248733b75e84f8bd1717c04 ("xfs: deferred inode inactivation")
https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git reserve-rt-metadata-space
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: 60s
fs: xfs
class: filesystem
test: dentry
cpufreq_governor: performance
ucode: 0x5003003
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
Details are as below:
