Jay Zhuang 29102641dd Skip directory fsync for filesystem btrfs (#8903) ... Summary: Directory fsync might be expensive on btrfs and it may not be needed. Here are 4 directory fsync cases: 1. creating a new file: dir-fsync is not needed on btrfs, as long as the new file itself is synced. 2. renaming a file: dir-fsync is not needed if the renamed file is synced. So an API `FsyncAfterFileRename(filename, ...)` is provided to sync the file on btrfs. By default, it just calls dir-fsync. 3. deleting files: dir-fsync is forced by set `IOOptions.force_dir_fsync = true` 4. renaming multiple files (like backup and checkpoint): dir-fsync is forced, the same as above.
