Greeting, FYI, we noticed a -23.7% regression of stress-ng.dir.ops_per_sec due to commit: commit: 01e8f379a4895a9a173391408db4fb49ec91e148 ("xfs: flush inode inactivation work when compiling usage statistics") https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git master in testcase: stress-ng on test machine: 96 threads 2 sockets Intel(R) Xeon(R) Gold 6252 CPU @ 2.10GHz with 512G memory with following parameters: nr_threads: 10% disk: 1HDD testtime: 60s fs: xfs class: filesystem test: dir cpufreq_governor: performance ucode: 0x5003006 If you fix the issue, kindly add following
