  	  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.
