The zstd command line tool can decompress gzip/zlib compressed data, and
can compress in the gzip format. However, the zstd format is not compatible
with zlib, so gzip/zlib cannot decompress zstd compressed data. The zstd
kernel module can only compress and decompress the zstd format, and can't
decompress zlib/gzip compressed data.
