Subject: [fanotify] a23a7dc576: unixbench.score -3.7% regression
Greeting,
FYI, we noticed a -3.7% regression of unixbench.score due to commit:
commit: a23a7dc57615679ee21ac350c36bde4f863ab249 ("[RFC][PATCH] fanotify: introduce filesystem view mark")
url: https://github.com/0day-ci/linux/commits/Amir-Goldstein/fanotify-introduce-filesystem-view-mark/20201110-020535
base: https://git.kernel.org/cgit/linux/kernel/git/jack/linux-fs.git fsnotify
in testcase: unixbench
on test machine: 96 threads Intel(R) Xeon(R) CPU @ 2.30GHz with 128G memory
with following parameters:
runtime: 300s
nr_task: 30%
test: pipe
cpufreq_governor: performance
ucode: 0x4002f01
test-description: UnixBench is the original BYTE UNIX benchmark suite aims to test performance of Unix-like system.
test-url: https://github.com/kdlucas/byte-unixbench
If you fix the issue, kindly add following tag
Reported-by: kernel test robot <oliver.sang@...el.com>
Details are as below:
