324 			 the automaic compression and gives the user discretion of

929 Compression mode
932 f2fs supports "fs" and "user" compression modes with "compression_mode" mount option.
934 compression enabled files (refer to "Compression implementation" section for how to
935 enable compression on a regular inode).
938 This is the default option. f2fs does automatic compression in the writeback of the
939 compression enabled files.
942 This disables the automatic compression and gives the user discretion of choosing the
943 target file and the timing. The user can do manual compression/decompression on the
944 compression enabled files using F2FS_IOC_DECOMPRESS_FILE and F2FS_IOC_COMPRESS_FILE
