In linux kernel since version 2.6.38 (release Date: 2011-03-14)  
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.
