| 5 | LZMA2 compression algorithm and BCJ filters are supported using | |
| 6 | the .xz file format as the container. For integrity checking, | |
| 7 | CRC32 is supported. See Documentation/xz.txt for more information. | |

| 52 | This allows passing .xz files to the in-kernel XZ decoder via | |
| 53 | a character special file. It calculates CRC32 of the decompressed | |
| 54 | data and writes diagnostics to the system log. | |

| 56 | Unless you are developing the XZ decoder, you don't need this | |
| 57 | and should say N. |
