Linux 5.6 introduces an optional F2FS transparent data compression support, and through LZO algorithm compression and LZ4. Now, Linux 5.7 kernel is supporting Zstd compression algorithms.
F2FS defenders Jaegeuk Kim merged submitted by a Huawei engineer the patch to support Zstd compression algorithms, compression and support for file system level. This means that on Linux Kernel 5.7 and later, set compress_algorithm = zstd can enable Zstd compression when mounting F2FS file system.
Support for Zstd Huawei is one of the many patches submitted, in patches, the concern is that the default compression algorithm from LZO converted to LZ4. In other words, there is still support for LZO algorithm, but using default is LZ4. Because developers find LZ4 provide similar LZO compression, decompression, but much faster.
Finally, Linux 5.7 merge window will be launched in early April, and now this work has been developed as part of F2FS trees in the queue.
