- LZMA2 compression algorithm and BCJ filters are supported using
- the .xz file format as the container. For integrity checking,
- CRC32 is supported. See Documentation/xz.txt for more information.

- This allows passing .xz files to the in-kernel XZ decoder via
- a character special file. It calculates CRC32 of the decompressed
- data and writes diagnostics to the system log.
- Unless you are developing the XZ decoder, you don't need this
- and should say N.
