Subject: [RFC PATCH v3 13/22] fs: puzzlefs: Implement the initial version of PuzzleFS
Date: Thu, 16 May 2024 22:03:36 +0300
Message-Id: <20240516190345.957477-14-amiculas@cisco.com>

Implement the file system trait fs::FileSystem for PuzzleFS, directory
iteration, inode lookup and the read_folio operations. The puzzlefs
image path and the manifest digest are hard-coded for now due to the
lack of module parameters support.

Puzzlefs uses capnproto for storing the filesystem metadata, defined in
manifest.capnp and metadata.capnp. The files manifest_capnp.rs and
metadata_capnp.rs were generated with (Cap'n Proto version 0.10.4):
```
capnp compile -orust manifest.capnp
capnp compile -orust metadata.capnp
```
, formatted with rustfmt and I have also added the following line:
```
 #![allow(unreachable_pub)]
 #![allow(dead_code)]
```
to avoid warnings.

capnp version used:
```
$ capnp --version
Cap'n Proto version 0.10.4

$ cargo install --list | grep capnp
capnpc v0.18.0:
    capnpc-rust
    capnpc-rust-bootstrap
```

Ideally, manifest_capnp.rs and metadata_capnp.rs should be automatically
generated at build time. However, this means the capnp binary becomes a
dependency for the build and I didn't want this. Besides, the metadata
schemas are not expected to change frequently, so it's acceptable to
manually regenerate the two rust files when this happens.

The code is adapted from the puzzlefs FUSE driver [1]. The data
structures required for the filesystem metadata are defined in types.rs.
Each structure has a `from_capnp` method used to convert between the
capnp memory layout and the native Rust structures.  This leaves room
for improvement [2].

inode.rs implements the PuzzleFS structure which contains a list of
metadata layers.
