f2fs: add F2FS_IOC_GET_COMPRESS_OPTION ioctl
Added a new F2FS_IOC_GET_COMPRESS_OPTION ioctl to get file compression
option of a file.
struct f2fs_comp_option {
u8 algorithm; => compression algorithm
=> 0:lzo, 1:lz4, 2:zstd, 3:lzorle
u8 log_cluster_size; => log scale cluster size
=> 2 ~ 8
};
struct f2fs_comp_option option;
ioctl(fd, F2FS_IOC_GET_COMPRESS_OPTION, &option);
