	help
	  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.

	help
	  MicroLZMA is a header format variant where the first byte
	  of a raw LZMA stream (without the end of stream marker) has
	  been replaced with a bitwise-negation of the lc/lp/pb
	  properties byte. MicroLZMA was created to be used in EROFS
	  but can be used by other things too where wasting minimal
	  amount of space for headers is important.

Unless you know that you need this, say N.

	  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.
