Subject: [linus:master] [keys] 9578e327b2: stress-ng.key.ops_per_sec -98.9%
regression
Hello,
kernel test robot noticed a -98.9% regression of stress-ng.key.ops_per_sec on:
commit: 9578e327b2b4935a25d49e3891b8fcca9b6c10c6 ("keys: update key quotas in key_put()")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
test machine: 64 threads 2 sockets Intel(R) Xeon(R) Gold 6346 CPU @ 3.10GHz (Ice Lake) with 256G memory
parameters:
nr_threads: 100%
testtime: 60s
test: key
cpufreq_governor: performance
If you fix the issue in a separate patch/commit (i.e. not just a new version of
the same patch/commit), kindly add following tags
| Reported-by: kernel test robot <oliver.sang@...el.com>
