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.
