Subject: [linus:master] [maple_tree] 9b60811cb3:
will-it-scale.per_process_ops 24.7% regression
Hello,
kernel test robot noticed a 24.7% regression of will-it-scale.per_process_ops on:
commit: 9b60811cb3b42fe9a8e3f0aa3e007cd9cc814a78 ("maple_tree: Use kfree_rcu in ma_free_rcu")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
[still regression on linus/master e406d57be7bd2a4e73ea512c1ae36a40a44e499e]
[still regression on linux-next/master 7396732143a22b42bb97710173d598aaf50daa89]
testcase: will-it-scale
config: x86_64-rhel-9.4
compiler: gcc-14
test machine: 192 threads 2 sockets Intel(R) Xeon(R) 6740E CPU @ 2.4GHz (Sierra Forest) with 256G memory
parameters:
nr_task: 100%
mode: process
test: mmap2
cpufreq_governor: performance
