Subject: [linux-next:master] [mm] 3104138517: will-it-scale.per_process_ops
5.6% improvement
Hello,
kernel test robot noticed a 5.6% improvement of will-it-scale.per_process_ops on:
commit: 3104138517fc66aad21f4a2487bb572e9fc2e3ec ("mm: make vma cache SLAB_TYPESAFE_BY_RCU")
https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git master
testcase: will-it-scale
config: x86_64-rhel-9.4
compiler: gcc-12
test machine: 104 threads 2 sockets (Skylake) with 192G memory
parameters:
nr_task: 100%
mode: process
test: brk1
