Actually it seems the name, orphan_blkaddr, was wrong.
That should be orphan_blocks which is no need to fix like this.
Instead, I found there is another bug below.
> orphan_blkaddr = __start_sum_addr(sbi) - 1;
orphan_blocks = __start_sum_addr(sbi) - 1 -
le32_to_cpu(F2FS_RAW_SUPER(sbi)->cp_payload);
It may help to define a macro to get cp_payload.

The orphan_blocks is enough. No need to fix this.

ditto.
