Hello,
kernel test robot noticed a 4.5% improvement of stress-ng.rename.ops_per_sec on:
commit: 62334fab47621dd91ab30dd5bb6c43d78a8ec279 ("xfs: use per-mount cpumask to track nonempty percpu inodegc lists")
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master
testcase: stress-ng
test machine: 36 threads 1 sockets Intel(R) Core(TM) i9-9980XE CPU @ 3.00GHz (Skylake) with 32G memory
parameters:
nr_threads: 10%
disk: 1SSD
testtime: 60s
fs: xfs
class: filesystem
test: rename
cpufreq_governor: performance
In addition to that, the commit also has significant impact on the following tests:
