Ok. I was able to use the separate structs and then
In verity_end_io(), if bi_status is not BLK_STS_OK, it can be return
directly. But if FEC configured, it is desired to correct the data page
through verity_verify_io. And the return value will be converted to
blk_status and passed to verity_finish_io().
BTW, when a bit is set in v->validated_block

The kernel supports multi page bio vector entries, so we can use them in
dm-bufio as an optimization.
