All of them are using The Flexible Filesystem Benchmark (ffsb) - a filesystem performance measurement too [3]. Tests were contributed in 2009 and needs at least some cleanup. I wonder whether testing these features is still relevant. And if yes, whether they're covered in xfstests? After brief search in xfstests ext4 tests it doesn't look like, at least not directly. Does it make sense to you to keep them? (either to cleanup and keep them in LTP or rewrite and contribute to xfstests) List of these tests [3]: ext4-inode-version [4] ------------------ Directory containing the shell script which is used to test inode version field on disk of ext4. ext4-journal-checksum [5] --------------------- Directory containing the shell script which is used to test journal checksumming of ext4. ext4-nsec-timestamps [6] -------------------- Directory containing the shell script which is used to test nanosec timestamps of ext4. ext4-online-defrag [7] ------------------ Directory containing the shell script which is used to test online defrag feature of ext4. ext4-persist-prealloc [8] --------------------- Directory containing the shell script which is used to test persist prealloc feature of ext4. ext4-subdir-limit [9] ----------------- Directory containing the shell script which is used to test subdirectory limit of ext4. According to the kernel documentation, we create more than 32000 subdirectorys on the ext4 filesystem. ext4-uninit-groups [10] ------------------ Directory containing the shell script which is used to test uninitialized groups feature of ext4. Thanks for info.
