Subject: [mm/gup] a308c71bf1: stress-ng.vm-splice.ops_per_sec -95.6%
regression
Greeting,
FYI, we noticed a -95.6% regression of stress-ng.vm-splice.ops_per_sec due to commit:
commit: a308c71bf1e6e19cc2e4ced31853ee0fc7cb439a ("mm/gup: Remove enfornced COW mechanism")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
in testcase: stress-ng
on test machine: 96 threads Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 192G memory
with following parameters:
nr_threads: 100%
disk: 1HDD
testtime: 30s
class: pipe
cpufreq_governor: performance
ucode: 0x5002f01
If you fix the issue, kindly add following tag
