+         the .xz file format as the container. For integrity checking,

+         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.
