LZMA2 compression algorithm and BCJ filters are supported using |
|
the .xz file format as the container. For integrity checking, |
|
CRC32 is supported. See Documentation/staging/xz.rst 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.
