Add a extra field compress_flag to get/set more compress option from/to compressed inode.
Signed-off-by: Chao Yu <yuchao0@huawei.com> ---
Daeho, Jaegeuk,
Could you please check whether we could add this new field to struct f2fs_comp_option? so we can expand to allow user to query/config more options of compressed inode via new ioctl.
It needs to consider before original patches goes to merge window, let me know you have other concerns.
