--- Comment #4 from Chao Yu (chao@kernel.org) ---
Thanks for reminding that, IMO, yes, after we enable superblock checksum
feature, we can know which sb is corrupted, and try to recovery corrupted sb
with another good one.
Although, for your case, I guess the only corrupted field is
f2fs_super_block.cp_payload, which should be 0 instead of 1, as it can be
correctly hinted from checkpoint package fields that are under checksum
protection already.
So, w/o sb checksum feature, do you wish that we can have a try with recovering
sb fields from checkpoint pack?
