Added a new F2FS_IOC_SET_COMPRESS_OPTION_V2 ioctl to change file
compression option of a file.
struct f2fs_comp_option_v2 {
union {
struct {
__u8 algorithm;
__u8 log_cluster_size;
__u16 compress_flag;
};
struct f2fs_comp_option option;
};
};
struct f2fs_comp_option_v2 option;
option.algorithm = 2;
option.log_cluster_size = 2;
option.compress_flag = (5 << COMPRESS_LEVEL_OFFSET) | BIT(COMPRESS_CHKSUM);
ioctl(fd, F2FS_IOC_SET_COMPRESS_OPTION_V2, &option);

v2:
-export ZSTD_MAX_CLEVEL to avoid compile error
-handle COMPRESS_LZO and COMPRESS_LZORLE in f2fs_ioc_set_compress_option
-handle F2FS_IOC_SET_COMPRESS_OPTION_V2 in f2fs_compat_ioctl
