Subject: [akpm-mm:mm-stable] [memcg] d73d003521:
stress-ng.exit-group.ops_per_sec 118.0% improvement
Hello,
kernel test robot noticed a 118.0% improvement of stress-ng.exit-group.ops_per_sec on:
commit: d73d00352145fb51d31771047aa939850d87fa50 ("memcg: mm_update_next_owner: move for_each_thread() into try_to_set_owner()")
https://git.kernel.org/cgit/linux/kernel/git/akpm/mm.git mm-stable
testcase: stress-ng
test machine: 256 threads 2 sockets GENUINE INTEL(R) XEON(R) (Sierra Forest) with 128G memory
parameters:
nr_threads: 100%
testtime: 60s
test: exit-group
cpufreq_governor: performance
Details are as below:
