+ LZMA2 compression algorithm and BCJ filters are supported using

+ 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.
