Greeting, FYI, we noticed a -26.1% regression of stress-ng.dentry.ops_per_sec due to commit: commit: 752d5513e6e9f5128d3176e7d780f6b06bbb56f0 ("xfs: defer inode inactivation to a workqueue") https://git.kernel.org/cgit/linux/kernel/git/djwong/xfs-linux.git vectorized-scrub in testcase: stress-ng on test machine: 48 threads 2 sockets Intel(R) Xeon(R) CPU E5-2697 v2 @ 2.70GHz with 112G memory with following parameters: nr_threads: 10% disk: 1HDD testtime: 60s fs: xfs class: filesystem test: dentry cpufreq_governor: performance ucode: 0x42e In addition to that, the commit also has
