No particular use case yet. Ocfs2 could be considered as option if it outperforms xfs/ext4 under osd - therefore question. It just seemed suitable as it can be considered stable(as xfs,ext4) and has unlimited xattrs. Regarding zfs - at times it seems that it is closer to production on linux and matures faster than btrfs.
