Hi Chao, Could you please add this into Junling's patch series? A little bit confusing between patches and reviews on them.

[f2fs-dev] [PATCH] fsck.f2fs: try to recover cp_payload from valid cp pack
If sb checksum is not enabled, and cp pack is valid due to no crc inconsistence, let's try to recover cp_payload based on cp_pack_start_sum in cp pack.
