  In-kernel EROFS has been fully compatible with RAFS v6 image format since Linux 5.16. In other words, uncompressed RAFS v6 images can be mounted over block devices since then.
  -Since [Linux 5.19](https://lwn.net/Articles/896140), EROFS has added a new file-based caching (fscache) backend. In this way, compressed RAFS v6 images can be mounted directly with fscache subsystem, even such images are partially available. In the future, `estargz` and `zstd::chunked` can be converted on the fly and mounted in this way too.
