| 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. |
