What about introduce DATA_POR and use it here?

And in f2fs_is_valid_blkaddr(), we can handle this case as:

	case META_POR:
	case DATA_POR:
		if (unlikely(blkaddr >= MAX_BLKADDR(sbi) ||
			blkaddr < MAIN_BLKADDR(sbi)))
			return false;
		break;

>   			*is_detecting = false;
> -			return 0;
> +			return -EFSCORRUPTED;

I guess we should not return EFSCORRUPTED, because blkaddr_fast can be
invalid as we expect.

It's not needed, because there will be no checkpoint to persist the flag.

I guess we should not return EFSCORRUPTED, because blkaddr can be
invalid as we expect.
