2 tristate "XZ decompression support"
5 LZMA2 compression algorithm and BCJ filters are supported using
6 the .xz file format as the container. For integrity checking,
7 CRC32 is supported. See Documentation/xz.txt for more information.

48 tristate "XZ decompressor tester"
52 This allows passing .xz files to the in-kernel XZ decoder via
53 a character special file. It calculates CRC32 of the decompressed
54 data and writes diagnostics to the system log.
56 Unless you are developing the XZ decoder, you don't need this
