This restores the old behavior that existed before 2013-02-22, when changes were made by64dbfb444c("decompressors: drop dependency on CONFIG_EXPERT") and5dc49c75a2("decompressors: make the default XZ_DEC_* config match the selected architecture"). Disabling the filters only makes sense on embedded systems.

LZMA2 compression algorithm and BCJ filters are supported using

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

CRC32 is supported. See Documentation/xz.txt for more information.

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.
