| 54 | This allows passing .xz files to the in-kernel XZ decoder via |
| 55 | a character special file. It calculates CRC32 of the decompressed |
| 56 | data and writes diagnostics to the system log. |

| 58 | Unless you are developing the XZ decoder, you don't need this |
| 59 | and should say N. |
