298 compression on those corresponding files, e.g. if all files
299 with '.ext' has high compression rate, we can set the '.ext'
300 on compression extension list and enable compression on
302 For other files, we can still enable compression via ioctl.
304 can be set to enable compression for all files.
306 compression on those corresponding files, just contrary to compression extension.

318 compress_mode=%s Control file compression mode. This supports "fs" and "user"
319 modes. In "fs" mode (default), f2fs does automatic compression
320 on the compression enabled files. In "user" mode, f2fs disables
321 the automaic compression and gives the user discretion of
323 compression/decompression on the compression enabled files using

919 compression enabled files (refer to "Compression implementation" section for how to
920 enable compression on a regular inode).
923 This is the default option. f2fs does automatic compression in the writeback of the
924 compression enabled files.
927 This disables the automatic compression and gives the user discretion of choosing the
928 target file and the timing. The user can do manual compression/decompression on the
929 compression enabled files using F2FS_IOC_DECOMPRESS_FILE and F2FS_IOC_COMPRESS_FILE
